Oh and also, while editing on the pedal, which is how I always work, pull down the menu, 1st page, bottom row centre, Edit All button.
It's almost perfect. It allows you to work from one screen without going back and forth to the main menu. Why only almost? No shortcut to change the order of effects. Otherwise it's great.
The little red squares above the effects are on off switches, which I also didn't know.
