One of my favorite new features in Leopard is the ability to search all of the menus in a given application. This is extremely helpful when you don’t want to dig through a whole much of nested menus to find the item you’re looking for.
If you’ve read my other posts, you know that I’m big into keyboard shortcuts and hotkeys. Here’s how to open up the help-menu without using your mouse 
Command + Shift + /
Or you can think of it as
Command + ?
Note that this doesn’t work in some applications (e.g. FireFox, which is just one more reason for me to switch over to Safari…)
