I'd be lost without the navigation pane, at least when I'm working on this huge honking manuscript. But I did try it your way. When I called up the pane with Ctrl + F, it showed up right away -- but the outline was still expanded. To make this a little, clearer, this image shows you the default navigation pane with everything expanded (on the left) and the pane after I went through and collapsed every segment by clicking on all the little triangles. What I would like (and it sounds less likely all the time) is to be able to have the default view on the nav pane collapsed, so I could jump from chapter to chapter more quickly.
Am I the only person in the Word universe with this problem?
And thanks again, I appreciate your help.
