Hi
I use quite a few softwares that, like madmapper, require you to know the fullscreen/desktop mode keyboard shortcuts. This is because in complex video output scenarios you can occasionally find yourself stuck with the fullscreen output on your UI monitor.
I've never understood why the MM shortcuts are +t and +u, perhaps they resemble something meaningful in a European language but as an english user it's never in the first couple that I try.
Even if the shortcut doesn't denote its meaning, can it please be one shortcut that toggles?
