Keyboard Maestro interfering with control-tab action in browsers - how to disable? I've just purchased Keyboard Maestro, and now when I am in a browser and click control-tab, I can no longer advance through the open tabs of the browser the way I did before. That key combination must be used in KM to do something, and that's pre-empting the system shortcut.

How can I find out what action is attached to that keystroke in KM (so I can either change it or disable it)?
Open Maestro Switcher

All Macros -> Activate Window Swicher



And you can change or remove  it from there. (click at "-" at the bottom)
