Mute group Keys These keys map to the on-screen 4x8 grid. They are used for toggling multiple patterns (a "mute group") at once. It is generally good to lay them out to match the pattern hot keys. When group-learn is initiated, the next keystroke is automatically shifted, so that "1" becomes "!", "a" becomes "A", etc. This makes it easy to use the learn keys. Another difference from the hot-keys is that there are always 32 mute-groups available, no matter the set size or layout. Note that these keys are configurable in the 'ctrl' file. But one won't generally want to change them except to adapt to a non-US keyboard.
