How do I set Command-Tab as the trigger for Witch? I'm using the app switcher, Witch, and I can't figure out how to set it to activate on Command-Tab. When I try to capture the keys, the OS switches apps on me. I can set Witch to activate on Option-Tab without issue.
I'm adding this because it took me a couple  weeks to find it:

Instead of trying to capture the key combination for Command-Tab, click the gear icons next to the Keyboard fields on the Witch preferences pane. It will give you options for setting the trigger to Command-Tab or Command-Shift-Tab.
