We want to use one set for ASCII, ScanCodes and ScreenCodes. 0 -63 : 64 -127 : SHIFT 128-191 : CTRL 192-256 : CTRL+SHIFT No more ALT key in TempleOS. CTRL-LEFT/RIGHT is already begin/end line. CTRL-UP/DOWN is already top/bottom of document. What about function keys? We will use reduced keyboard, probably.
