Word 2007:  Is it possible to change the line length for a given heading? 

Basically I have a heading with text in it that drops onto another line, I need it to be all one line.


Go to File/Options/Advanced, you can scroll down to the "Show document content" category and check the box for "Show text wrapped in the document window".
