On //GS's, you can tell when the control key is down, or when either shift key (but you can't tell the difference) is down, or if the capslock key is down. I don't know offhand if these can be detected independently, or if you have to read the register after a keystroke (ie, the modifier was down in tandem with a real key). This same register also notes the Open Apple and Option key states and whether the last key hit is one the keypad (includes function keys). -- Dave Whitney Computer Science MIT 1990 | I wrote Z-Link and BinSCII.
