This chapter covers the more advanced tools for working with text in Writer:

This chapter assumes that familiarity with the basic text techniques described in Chapter 2, Working with Text: Basics. We also recommend displaying formatting aids, such as end-of-paragraph marks, tabs, breaks, and other items in Tools > Options > LibreOffice Writer > Formatting Aids. For information on formatting text, see Chapter 4.

Using built-in language tools

Writer provides some tools that make work easier if you mix multiple languages within the same document or if you write documents in various languages:

The main advantage of changing the language for a text selection is that you can then use the correct dictionaries to check spelling and apply the localized versions of AutoCorrect replacement tables, thesaurus, and hyphenation rules. A grammar checking dictionary may also be available for the selected language.

You can also set the language for a paragraph or a group of characters as None (Do not check spelling). This option is especially useful when you insert text such as web addresses or programming language snippets that you do not want to check for spelling.

Using Tools > Language

You can set the language for the whole document, for individual paragraphs, or even for individual words and characters, in Tools > Language on the Menu bar (Figure 1):

The Reset to Default Language option on the submenu is the fastest way to return a selection, paragraph, or all text to the default language set in Tools > Options (described below).

The Tools > Language menu options include two that are activated when Asian is selected in Tools > Options > Language Settings > Languages > Default languages for documents: Chinese Conversion and Hangul/Hanja Conversion. These options are not covered in this book.

Figure 1: Options available through Tools > Language on the Menu bar

Options available through Tools > Language on the Menu bar

Using language settings in Options

Another way to change the language of a whole document is to use Tools > Options > Language Settings > Languages (macOS: LibreOffice > Preferences > Language Settings > Languages). In the Default languages for documents section (Figure 2), you can choose a language for all the text that is not explicitly marked as a different language.


A change in the default language from the Options dialog is a general change of settings of LibreOffice and will therefore apply to all the documents created in the future. To change the language for the current document only, be sure to select the For the current document only option (Figure 2).

Figure 2: Options in the Languages settings

Options in the Languages settings


The spelling checker works only for those languages in the list that have a checkmark symbol next to them. If you do not see this symbol next to your preferred language, you can install the dictionary using Tools > Language > More Dictionaries Online.

Using paragraph and character styles

Changing the language on the Font tab of the Paragraph Styles dialog (Figure 3) will change the language for all paragraphs that use that paragraph style. To include whole paragraphs in different languages in a single document, you can use a different paragraph style for each language. For example, you might define BodyText-EN and BodyText-FR in a document containing paragraphs in both English and French.

See Chapter 9, Working with Styles, for more information on how to manage the language settings of a style.

Figure 3: Setting the language for a paragraph style

Setting the language for a paragraph style

Using the Status bar

To set paragraphs to be checked in a language that is different from the language of the rest of the document, you can put the cursor in the paragraph (or select more than one paragraph) and change the language on the Status bar (Figure 4). This change affects only the selected paragraphs.

The language used for checking spelling is also shown in the Status bar, next to the page style in use. You can change the language for the paragraph or the entire document; click the language in the Status bar to pop up a menu of choices.

Figure 4: Language choices on the Status bar

Language choices on the Status bar

The Reset to Default Language option on the menu and submenu is the fastest way to return a paragraph or the entire document to the default language set in Tools > Options.

Advanced find and replace techniques

In addition to finding and replacing words and phrases (described in Chapter 2), you can use Writer’s Find and Replace dialog to find and replace paragraph styles and text formatting.

Find and replace paragraph styles

Combining material from several sources may result in unwanted paragraph styles in a document. To quickly change all the paragraphs from one style to another (preferred) style:

1)  On the Find and Replace dialog with Other Options displayed, select Paragraph Styles. The Find and Replace boxes now contain a list of paragraph styles in use in the document.

2)  If you have text formats or attributes specified, this option is labeled Including Styles. Select No Format to remove any attributes and return the option to Paragraph Styles.

3)  Select the styles you want to search for and replace.

4)  Click Find, Find All, Replace, or Replace All.

Repeat steps 2 and 3 for each style that you want to replace.

Find and replace text formatting

Unlike Find and Replace for paragraph styles described above, the formats or attributes to be searched for do not appear inside the Find or Replace box. Instead, the formats or attributes to be found or replaced appear below the Find and Replace boxes (Figure 5). Clicking on the down-arrow to the right does not bring up options.

Figure 5: Find and replace text formatting

Find and replace text formatting

To find a type of formatting in the document, follow this procedure:

1)  Open the Find and Replace dialog (Figure 5) and select Other options.

2)  To clear any previous format criteria, place the cursor in the Find box and then click the No Format button. To clear the selected Replace options, place the cursor in the Replace box and click the No Format button.

3)  Click the Format button to open the Search for Formatting dialog, which looks much like the Character dialog. Select a format from any of the tabs (for example: bold, 14 pt, Spacing above paragraph).

4)  To find this format that has been applied only by direct formatting, leave the Including Styles box unchecked. To find this format also applied inside a character or paragraph style, select the Including Styles box.

5)  Choose Find All to have all formats found highlighted. Choose Find Previous or Find Next to find one format instance at a time.

6)  To replace the chosen format, click inside the Replace box, then choose Format and choose a replacement from the tabbed options.

7)  Replace the formats one at a time using Find Previous > Replace or Find Next > Replace. Use Replace All to change all formats at once.

8)  To avoid errors the next time you use this dialog, it is a good idea to repeat Step 2 and clear all the formatting criteria selected.

To change the formatting for a specific word or phrase in a document:

1)  Type the word or phrase in the Find box.

2)  In the Replace box, type in the new text you want to use and choose the formats you would like to change. However, if you want to keep the same word or phrase and only change its format, ensure you also type the word or phrase in the Replace box. Otherwise, Writer will remove the word or phrase from the document.

3)  Replace the words and formats one at a time using Find Previous > Replace or Find Next > Replace. Use Replace All to change all words and formats at once.

Similarity search

This option finds terms that are similar to the Find: text. For example, a similarity search can find words that differ by two characters.

Select Similarity search and click the Similarities button to open a dialog where you can modify the text search by length and number of characters different from the search term (Figure 6).

Figure 6: Similarity search dialog

Similarity search dialog

Exchange characters

Enter the number of characters in the search term that can be exchanged. For example, if you specify 2 exchanged characters, "black" and "crack" are considered similar.

Add characters

Enter the maximum number of characters by which a word can exceed the number of characters in the search term.

Remove characters

Enter the number of characters by which a word can be shorter than the search term.


Searches for a term that matches any combination of the similarity search settings.

Search with wildcards and regular expressions

A wildcard is a special character that represents one or more unspecified characters. Wildcards make text searches more powerful but often less specific. LibreOffice enables you to use combinations of characters known as regular expressions which are more specific than simple wildcards but less so than a literal string. Regular expressions are very powerful but not very intuitive. They can save time and effort by combining multiple finds into one.

Table 1 shows a few of the regular expressions used by LibreOffice. The Help describes many more regular expressions and their uses.

To use wildcards and regular expressions when searching and replacing:

1)  On the Find and Replace dialog, click Other Options to see more choices. On this expanded dialog, select the Regular expressions option.

2)  Type the search text, including the wildcards, in the Search for box and the replacement text (if any) in the Replace with box. Not all regular expressions work as replacement characters; the line break (\n) is one that does work.

3)  Click Find, Find All, Replace, or Replace All (not recommended).

Table 1: Examples of search wildcards (regular expressions)

To find

Use this expression

Examples and comments

Any single character

. (a period or full stop)

b.d finds bad, bud, bid, and bed.

One of the specified characters


b[iu]n finds bin and bun.

Any single character in this range


[r-t]eed finds reed, seed, and teed; ranges must be in alphabetically ascending order.

Any single character except the characters inside the brackets


p[^a]st finds post and pest, but not past.

The beginning of a word


\<log finds logbook and logistics, but not catalog.

The end of a word


log\> finds catalog, but not logistics.

A paragraph marker


Does not work as a replacement character. Use \n instead.

A line break


Finds a line break that was inserted with Shift+Enter. When used as a replacement character, it inserts a paragraph marker.


To search for a character that is defined as a wildcard, type a backslash (\) before the character to indicate that you are using it literally. For example, to find the text $5.00, you would conduct a search using \$5\.00.

Tracking changes to a document

You can use several methods to keep track of changes made to a document:

This section describes the use of change tracking features, which include:


Not all changes are recorded. For example, changing a tab stop from align left to align right, and changes in formulas (equations) or linked graphics are not recorded.

Preparing a document for review

When you send a document to someone else to review or edit, you may want to prepare it first so that the editor or reviewer does not have to remember to turn on the revision marks. After you have protected the document, any subsequent user must enter the correct password in order to turn off protection or accept or reject changes.

1)  Open the document. Check whether it contains multiple versions by clicking File > Versions. If multiple versions are listed, save the current version as a separate document with a different name and use this new document as the review copy.

2)  With the review copy open, make sure that change recording is turned on. The Edit > Track Changes > Record Menu bar item and the Record Track Changes icon on the Track Changes toolbar are highlighted when recording is turned on.

3)  Click Protect Track Changes on the Track Changes toolbar or select Edit > Track Changes > Protect on the Menu bar. On the Enter Password dialog that opens, type a password (twice) and click OK.


An alternative to steps 2 and 3 above is to choose File > Properties > Security tab, select the Record changes option, then click Protect and enter the password.

Track Changes menu and toolbar

In addition to the Track Changes menu (Figure 7), Writer provides a convenient toolbar (Figure 8) that includes buttons for the same functions. To enable the Track Changes toolbar, click View > Toolbars > Track Changes. You can dock this toolbar in a convenient place or leave it floating.

Recording changes

To begin recording (tracking) changes, click Record Track Changes on the Track Changes toolbar or select Edit > Track Changes > Record on the Menu bar. To show or hide the display of changes, click Show Track Changes on the Track Changes toolbar or select Edit > Track Changes > Show on the Menu bar.

To enter a comment on a tracked change, place the cursor in the area of the change and then click Edit > Track Changes > Comment or click the Insert Track Change Comment button (not the Insert Comment button) on the Track Changes toolbar.

To stop recording changes, click Edit > Track Changes > Record again.


See also “Adding other comments” on page 1 for a way to annotate text that is not associated with a tracked change.

Recording inserted, deleted, and moved material

By default, inserted text is underlined, deleted text has a line through it (strike through), both are in color, and a mark (change bar) appears in the margin. To modify the default settings, see Chapter 20, Customizing Writer.

In an existing table, a deleted row is shown in pink and an inserted row in cyan. A new, blank table is marked in the margin but the rows are not colored.

Moved material is shown in green and indicated by a double underline (new location) or double strikethrough (old location).

Recording changes of paragraph styles and other formatting

When a different paragraph style is applied to a paragraph, the change is indicated by a mark in the margin.

By default, a change of character style or a manually applied character attribute is indicated by bold, colored text in addition to the attribute (such as italic or underlined), and the change in indicated by a mark in the margin.

Changes in list numbering show the original list numbers of all list items as well as the new numbers. Some examples are shown in Figure 9.

Figure 9: Examples of recorded list numbering changes

Examples of recorded list numbering changes

Outline tracking

Outline tracking uses the Navigator to track changes in the sequence of entire portions of a document: a heading and any material between it and the next heading of the same level. With Track Changes enabled, using the Move Heading Up and Move Heading Down buttons on the Navigator causes the moved material to be marked and tracked in the same way as material moved using drag-and-drop or cut-and-paste.

Outline tracking is enabled by default. To disable it, right-click on any heading in the Navigator and choose Off from the context menu.

Viewing changes and comments

Hold the mouse pointer over a tracked change to display a Help Tip showing the type of change, the author, date, and time of day for the change. If Extended Tips are enabled, any comments recorded for this change are also shown.

In addition to being displayed as an extended tip, recorded comments are shown in the list in the Manage Changes dialog (Figure 10). If no comment has been recorded for a change, the Comment field is blank.

To move from one tracked change to the next, use the Previous Change and Next Change icons on the Track Changes toolbar (Figure 8).

By default, tracked changes are displayed inline. To display either deletions or insertions in the margins instead, select from the Show Track Changes drop-down in the Track Changes toolbar (Figure 8).

Accepting or rejecting changes

To accept or reject recorded changes, use any of these tools:

Track Changes menu and toolbar

For quick and easy accepting and rejecting of changes, use the Track Changes toolbar (Figure 8), which includes buttons for the same functions as appear on the Edit > Track Changes submenu (Figure 7).

Right-click (context) menu

1)  If tracked changes are not showing, click the Show Track Changes icon on the Track Changes toolbar or select Edit > Track Changes > Show on the Menu bar.

2)  Hover the mouse pointer over a recorded change. A box appears with information about the type of change, who made it, and the date and time.

3)  Right-click the changed text. In the context menu, choose Accept Change or Reject Change.

Manage Changes dialog and Sidebar deck

1)  Click the Manage Track Changes icon on the Track Changes toolbar or select Edit > Track Changes > Manage on the Menu bar. The Manage Changes dialog (Figure 10) opens, showing changes that have not yet been accepted or rejected. Or, click the Manage Changes icon in the Sidebar to display the same information.

2)  When you select a change in the dialog, the change itself is highlighted in the document, so you can see what was changed.

3)  Click Accept or Reject to accept or reject the selected change. You can also click Accept All or Reject All if you do not want to review the changes individually.

Figure 10: The List tab of the Manage Changes dialog

The List tab of the Manage Changes dialog

To show only the changes of certain people or only the changes on specific days or various other restrictions, use the Filter tab (Figure 11) on the Manage Changes dialog. After specifying the filter criteria, return to the List tab to see those changes that meet your criteria.

Figure 11: Filter page of Manage Changes dialog

Filter page of Manage Changes dialog

Comparing documents

Sometimes reviewers may forget to track the changes they make. You can find the changes if you compare the original document and the one that is edited. To compare them:

1)  Open the edited document. Select Edit > Track Changes > Compare Document or click the Compare Non-Track Changed Document icon on the Track Changes toolbar.

2)  A file browser dialog opens. Select the original document and click Open.

Writer finds and marks the changes and displays the Manage Changes dialog. From this point, you can go through and accept or reject changes as described earlier.

To set the level of detail used by this feature, go to Tools > Options > LibreOffice Writer > Comparison. See Chapter 20, Customizing Writer.

Merging modified documents

The processes discussed to this point are effective when you have one reviewer at a time. Sometimes, however, multiple reviewers all return edited copies of a document. Writer provides a facility to merge documents containing tracked changes into the original document, but the condition for making this work is very specific: the edited documents may differ only and exclusively in the recorded changes – all other original text must be identical.

To merge documents, all of the edited documents (but not the original document) need to have recorded changes in them.

1)  Open the original document into which you want to merge all copies.

2)  Click Edit > Track Changes > Merge Document or click the Merge Track Changed Document icon on the Track Changes toolbar. A file selection dialog opens.

3)  Select the edited copy of the document to be merged with the first. If there have been no subsequent changes to the original document, the copy is merged into the original.

4)  If any changes have been made to the original document, an error dialog appears that informs you that the merge is unsuccessful.

5)  After the documents merge, you will see the recorded changes from the copy in the original document.

6)  Repeat until all copies are merged.

All recorded changes are now included in the open copy. Save this file under another name.

Adding other comments

Writer provides another type of comment, which authors and reviewers can use to exchange ideas, ask for suggestions, or mark items needing attention.

You can select a block of text, including multiple paragraphs, to be highlighted for a comment, or you can insert a comment at a single point. To insert a comment, select the text, or place the cursor in the place the comment refers to. Right-click and choose Insert > Comment or press Ctrl+Alt+C or click the Insert Comment button (not the same as the Insert Track Change Comment button) on the Track Changes toolbar.

The anchor point of the comment is connected by a dotted line to a box on the right-hand side of the page where you can type the text of the comment. A Comments button is also added to the right of the horizontal ruler (Figure 12); you can click this button to toggle the display of the comments on and off.

Writer automatically adds the author’s name and a time stamp indicating when the comment was created. Select Tools > Options > LibreOffice > User Data to enter or change the name you want to appear in the Author field of the comment.

When you are finished typing the comment, click somewhere else on a page of the document. Otherwise, you will not be able to move away from the comment box.

If more than one person edits the document, each author is automatically allocated a different background color. Figure 12 shows an example of text with comments from two different authors. If an author selects text that overlaps another author’s comments, then the comments from the second author are nested with those of the first author.

Figure 12: Comments in LibreOffice Writer

Comments in LibreOffice Writer

Right-click on a comment, or click the arrow in the lower left, to open a context menu where you can delete the current comment, the whole current comment thread, all the comments from the same author, or all the comments in the document. From this menu, you can also choose Format all comments to open a dialog to apply some basic formatting to the text of the comment. You can also change font type, size, and alignment on the Menu bar.

When the document has been reviewed and commented and requires your action, you can mark each comment Resolved or Unresolved, using options on the comment’s context menu. When you mark a comment resolved, the word Resolved is inserted under the date in the comment box. You can toggle the display of all resolved comments in the document by using View > Resolved Comments on the Menu bar. You can also add an answer to the comment.

To navigate from one comment to another, open the Navigator (F5), scroll to find and expand the Comments section. Double-click the comment text to move the cursor to the anchor point of the comment in the document.

You can also navigate the comments by selecting Comment in the Navigate By box at the top of the Navigator and clicking the Up and Down arrows next to it, to move to the next or previous comment. You can also navigate use the keyboard: Ctrl+Alt+Page Down moves to the next comment and Ctrl+Alt+Page Up moves to the previous comment.

To print the comments in a document, choose one of the options in the Comments drop-down list in the Print dialog (File > Print > LibreOffice Writer tab): Comments only, Place at end of document, Place at end of page, Place in margins (Figure 13).

Figure 13: Options for printing comments

Options for printing comments

Using footnotes and endnotes

Footnotes appear at the bottom of the page on which they are referenced. Endnotes are collected at the end of a document.

To work effectively with footnotes and endnotes, you need to:

Inserting footnotes and endnotes

To insert a footnote or an endnote:

1)  Position the cursor where you want the footnote or endnote marker to appear.

2)  Select Insert > Footnote and Endnote on the Menu bar and choose Footnote or Endnote, or click the Insert Footnote or Insert Endnote button on the Standard toolbar.

3)  A footnote or endnote marker is inserted in the text and, depending on your choice, the cursor is relocated either to the footnote area at the bottom of the page or to the endnote area at the end of the document. Type the footnote or endnote content in this area.

To change the default Footnote/Endnote settings, go to Tools > Footnotes and Endnotes on the Menu bar.

To choose whether to use the automatic numbering sequence specified in the footnote settings or specify a custom number, go to Insert > Footnote and Endnote > Footnote or Endnote on the Menu bar to open the Insert Footnote/Endnote dialog (Figure 14).

You can edit an existing footnote or endnote in the same way you edit any other text.

To delete a footnote or endnote, delete the footnote marker. The contents of the footnote or endnote are deleted automatically, and the numbering of other footnotes or endnotes is adjusted automatically.

Figure 14: Inserting a footnote or endnote

Inserting a footnote or endnote

Formatting footnotes and endnotes

To format the footnotes themselves, click Tools > Footnotes and Endnotes. On the Footnotes/Endnotes Settings dialog (Figure 15), choose preferred settings.

Defining footnote formatting

Linking to another part of a document

Typed cross-references to other parts of a document can easily get out of date if you reorganize the order of topics, add or remove material, or reword a heading. Writer provides two ways to ensure that references are up to date: hyperlinks and automatic cross-references. Both methods can be used to link to other parts of the same document or to another document.

Both methods have the same result: if you Ctrl+click the link when the document is open in Writer, you are taken directly to the cross-referenced item. However, they also have major differences:

Using cross-references

To ensure that the text of cross-references update if a heading, caption, or other linked item is reworded, use automatic cross-references. For details, see Chapter 17, Fields.

Using bookmarks

Bookmarks are listed in the Navigator and can be accessed directly from there with a single mouse click. In HTML documents, bookmarks are converted to anchors that you can jump to by hyperlink. You can also cross-reference to a bookmark. For more information, see Chapter 17.

Using hyperlinks

When you type text (such as website addresses or URL) that can be used as a hyperlink, and then press the spacebar or the Enter key, Writer automatically creates the hyperlink and applies formatting to the text (usually a color and underlining).

If this does not happen, you can enable this feature using Tools > AutoCorrect > AutoCorrect Options. On the Options tab, select the URL Recognition option.

If you do not want LibreOffice to convert a specific URL to a hyperlink, you can go to Edit > Undo on the Menu bar, or press Ctrl+Z immediately after the formatting has been applied, or place the cursor in the hyperlink, right-click, and select Remove Hyperlink in the context menu.

You can also insert hyperlinks to other parts of your document, to other documents or parts of documents, and to email addresses, using the Navigator and the Hyperlink dialog, and you can modify all hyperlinks using the Hyperlink dialog. For details, see Chapter 12, Creating HTML Files, in the Getting Started Guide.

The standard (default) behavior for activating hyperlinks within LibreOffice is to use Ctrl+click. To change this behavior, go to Tools > Options > LibreOffice > Security, click the Options button next to Security Options and Warnings, and deselect Ctrl-click required to open hyperlinks. If clicking in your links activates them, check that page to see if the option has been deselected.

Editing hyperlinks

To edit a hyperlink, click anywhere in the link text and then open the Hyperlink dialog by right-clicking and choosing Edit Hyperlink in the context menu, or clicking the Hyperlink icon on the Standard Toolbar, or choosing Edit > Hyperlink on the Menu bar. Make your changes and click Apply. If you need to edit several hyperlinks, you can leave the Hyperlink dialog open until you have edited all of them. Be sure to click Apply after each one. When you are finished, click Close.

To change the color of hyperlinks, go to Tools > Options > LibreOffice > Application Colors, scroll to Unvisited links and/or Visited links in the General section, select those options, pick the new colors, and click OK. This will change the color for all hyperlinks in all components of LibreOffice, which may not be what you want.

Rearranging headings and text using the Navigator

The Navigator (Figure 16) provides several ways to move headings and their associated text to another location in a document: by dragging, using icons, or using the context menu (Figure 17).

If necessary, click the expansion symbol (+ sign or arrow) to the left of a heading to expand the list of subheadings. To more easily find a required heading, change the Show Up to Outline Level selection to show only a few levels of headings.

To move a heading with its associated text and subsections up or down in the document, but not change the outline level of the heading, do one of the following:

To move only the selected heading and not the text associated with the heading, hold down the Ctrl key while dragging or clicking an icon or selecting from the context menu.

To change the outline level of a heading (for example, from Heading 2 to Heading 1 or Heading 3) and its associated subheadings, without changing the location of the headings, do one of the following:

To change the outline level of only the selected heading, but not its associated subheadings, hold down the Ctrl key while clicking the icon or selecting from the context menu.

Outline folding

Using outline folding, you can hide and show all content under headings, including text, images, tables, frames, shapes, and text boxes. In large documents, this feature can help you quickly scroll to the right position for editing and reading.


To enable this feature, go to Tools > Options > LibreOffice Writer > View (macOS: LibreOffice > Preferences > LibreOffice Writer > View) and select Show outline-folding buttons. Optionally select Include sub levels.

Using the Navigator

Open the Navigator (F5) and display the Headings entries. Right-click on a heading in the Navigator and select Outline Folding > Toggle from the context menu (Figure Error: Reference source not found) to hide or show the content between that heading and the next heading of the same level.

Using a mouse

Hover the mouse pointer over a heading to display a small arrow in the left margin to indicate that outline folding is enabled. A down arrow indicates the heading and its contents are visible. A right arrow indicates the heading has hidden contents.

Figure 18: Outline Folding marker


Press the Control key (Command on macOS). When the mouse pointer changes shape, click to hide or show the content between that heading to the next heading of the same level.

Saving, printing, and exporting folded contents

Documents saved in Open Document Format (.odt) will retain the current settings of hidden and shown contents. The document contents are not affected by the folding settings.


Hidden (folded) contents will not be printed or exported to PDF. To print or export the full document, be sure to toggle off outline folding.

Inserting material from other documents

You may wish to reuse material from other files in the document you are writing. For example, you might be writing a set of instructions that include some common paragraphs. You could, of course, retype or copy and paste the common paragraphs into each document. However, if the common paragraphs are edited, you may need to update that information in every document where it occurs.

Writer provides some tools for making these tasks easier:

To use the Navigator tools, first select the item you want to insert from the source document, then choose Insert as Link or Insert as Copy. You cannot create links or copies of graphics, OLE objects, references, or indexes using this method.

Insert as Link

Inserts the selected item as a link where you drag and drop in the current document. Text is inserted as a protected section, marked as linked to the source document. The content of the link is automatically updated when the source is changed. To manually update the links in a document, choose Tools > Update > Links.

Insert as Copy

Inserts an independent copy of the selected item where you drag and drop in the current document. Text is in a section, but it is not protected. Copied items are not updated when the source is changed. You can remove the section, leaving the contents as normal text.

Line numbering

Line numbers in the margin are often used in legal documents, poetry, and lists of programming code. Writer can insert line numbers in an entire document or for selected paragraphs. Line numbers are included when you print the document. You can also add a separator between line numbers. Figure 19 shows an example with numbering on every line.

You can choose how many lines are numbered (for example, every line or every tenth line), the numbering type, and whether numbers restart on each page. In addition, a text separator (any text you choose) can be set on a different numbering scheme (one every 12 lines, for example).

To add line numbers to an entire document, click Tools > Line Numbering and select the Show numbering option in the top left corner of the Line Numbering dialog (Figure 20). Then select any options you want and click OK.

Figure 19: Line numbering example

Line numbering example

Figure 20: Line Numbering dialog

Line Numbering dialog

To disable line numbering for the entire document, you can edit the Default Paragraph Style (because all paragraph styles are based on the Default Paragraph Style):

Disabling line numbering for a document

Alternatively, you can disable line numbering for specific paragraphs (while leaving most of them enabled) by selecting the paragraphs, choosing Format > Paragraph or right-clicking and choosing Paragraph > Paragraph on the context menu, then going to the Outline & List tab and deselecting Include this paragraph in line numbering.

You can also create a paragraph style that includes line numbering, and apply it to the paragraphs that you want to add line numbers to. For example, to number the lines of example code in a document, you will probably want to use a font or indentation that is different from normal text.

To specify the starting line number:

1)  Click in the paragraph and choose Format > Paragraph or right-click and choose Paragraph > Paragraph on the context menu.

2)  On the Outline & List tab, make sure Include this paragraph in line numbering is selected.

3)  Select Restart at this paragraph and enter a line number in the Start with box.

4)  Click OK.
