But it would be much better if you could use it on any screen - by having access to the keycommand of a supported keyboard, like my Apple A1016 Bluetooth keyboard ........... I would be very pleased if someone could make this possible.

If Apple managed to make this work, then surely our MorphOS developers can implement this also, and also for the Apple A1048 keyboard - which is a wired keyboard - with 2 USB ports, and has the same keyboard layout as the A1016. If there any others that might be supported, that I have not mentioned then if this is possible with these 2 models then it would of course be fantastic for any of the others to be supported as well.
