MultiClutch Keycodes

On MacBook Pro, I use MultiClutch to add some convenient gestures to my desktop. This application surely opens the potential of the multi-touch pad. However, I'm having trouble bind arbitrary hotkeys to various gestures, so I look into the source code and found that if you input the keycodes directly, you can setup any key bindings.

You can edit the file:
/Users/YourLogin/Library/Preferences/com.wonderboots.MultiClutchBindings.plist

These is my setting, in which you can find Command-Tab which is usually not allowed in the interface.
