A year ago on this blog, I looked at a method for forcing line breaks in your table of contents.
An alternative method for this is to make your Table of Contents editable. The steps are outlined below, however I caution you with this method – if you Update your Table of Contents, then you will lose your edits (see last screenshot below).
After you have added a table of contents in your document, you may find that you have long headings that require line breaks in better places than those imposed by OOo Writer.
Edit the Index
Right-mouse-click (or Ctrl-click) and select Edit Index/Table.
You will see the window below.

Right mouse click on the table of contents and select 'Edit Index/Table'
On the Index/Table tab, you will see the tick box labelled ‘Protected against manual changes’.
Untick this.
Edit the Index/Table Text

Now you can edit the text in the table
Add breaks (Shift+Enter) or change text as desired.
IMPORTANT NOTE
It is important to note that if you update the Index/Table, the changes you have just performed will disappear.

If you Update Index/Table, the changes will be removed.
The table of contents will revert to the original.

The Table of Contents will restore any changes if you update the TOC



My name is Stephanie Krishnan and I'm passionate about the way that open source software and its community can help small businesses and individuals with their productivity and lives. One of the biggest arguments I get from business owners, however, is lack of support options. I decided to put together my own support blog to help people be productive at various levels with one of my favourite open source alternatives: OpenOffice.org! I do this through tutorials, downloadable templates and answers to questions from readers!
