command+option+z should *not* be the shortcut to revert the current project
command+option+z is "step backward" in photoshop, undo basically. Why is it revert file in illustrator?! so many people have lost work because of this simple oversight.
It is not for me (but I am on Windows).
Revert is (was) bound to F12 for me, but I removed in in Keyboard Shortcuts long ago. Can you do the same? Ctrl+Alt+Z was empty for me form the beginning (taken now by a different command).
