In DeskTop, if you hold Open- and Solid-Apple there is a beep and everything freezes until the modifiers are released.
This is MGTK trying to start KeyboardMouse mode. Usually though, the mode is immediately exited. Sometimes (???) you can get it to stick, and steer the cursor around with arrow keys and click with the Apple keys.
This is shortcut is not documented in the MGTK references, and since it's broken it's not really useful. It also prevents using double-modifiers for shortcuts (eg Close > Close All, Open > Open and Close Parent).
There is an explicit KeyboardMouse command that apps can use to trigger this mode.
Given all of that, I'm tempted to first fix the immediate exit problem, but then disable the activation logic.
