using QWERTY keys dont seem to fullfill the designated features, or am i getting confused by double key layout?

are there more key shortcuts like that, cause trying to improve the "game speed" by using some key combos, maybe for different games?

can i get scumm to use fullscreen on p1i?

but can I, otherwise, deactivate the screensaver in the menue on a p1i?

Alt+Left+Right doesnt work for me!
actually nothing happens
Am I doing something wrong? using p1i with newest scumm version...

but when I hit different keys, some actions like "talk to" are high-lighted, so are there more key-combos like Alt+Left+Right?
