Is there a way to get text to automatically wrap at a point other than the right margin? I am doing a table of contents, and I need text to not overlap the page numbers. As an example:

2.3 Vertical view of an installed 18.9 liter pitfall with lid and flashing
above......................................................................................... .............. 1

Some of my titles are multiple lines and trying to manually keep any text from overlapping the page number has proved to be almost impossible.

Any help is much appreciated!
