Hi I just wanted to share this little mapping I've come up with:
:map <RightMouse> <LeftMouse>za It makes right-clicking on a fold toggle it opened/closed. Using the mouse wheel all the time to scroll around in GVim, I find this very useful for navigating big files, especially with automatic syntax- or indent-folding. Scroll, click (expand), read, click (collapse), scroll some more... Tobia
