Thanks a lot for this, Rhett7660. The only option listed in this text that is completely cursor free is number 1, which is the one I'm using. However, it doesn't allow me to move through documents as the text suggests. It only brings up a list of the open documents, and the only way I have managed to actually select one of them is by using the cursor. I've tried to combine this short cut with different other commands to see if there is another way to scroll though the documents and select one using the keyboard, but I haven't been able to find one so far.
Edited to add: I just fixed it, there was a setting in System Preferences that messed it up. I also just discovered the app exposé option, which is very useful.
