Is there a way to "fan-out" or display all the open windows at once so I can select a window that might be "behind" 3 or 4 other windows? (I'm running Windows 7.) In OS X, for example, you can press the F3 key. Was called "marquee", I think at one time? Is it "exposé" now? (Maybe vice-versa).

[edit] I can see that Alt-Tab is designed to let you select between multiple open windows--and while that will be useful--I was hoping for something that mimicked the OS X feature I was describing... Thoughts?

It DOES help, provided it plays nicely with DF. (I had a different desktop tool that provided the function I'm looking for--but seemed to confuse DF--my wallpapers would turn to white BGs after invoking it.)
