Using a Keyboard

GS2 maps your modern computer keyboard, as best it can, to Apple II Keyboard functions.

The below tables explain how this is done, where it isn't obvious.

NOTE: Some platforms "eat" keystrokes intended for the Apple II window. E.g. Control-ALT(OA)-ESC on Windows minimizes the window (it's control-ESC). On Windows, doing a mouse capture (F1) can also help capture these keystrokes and let them do the Apple II thing instead of the Windows thing.

Key	Platform	Action
F1	All	Release mouse cursor when captured by window
F2	All	Toggle between Composite; RGB; and Monochrome displays
F3	All	Toggle between fullscreen and windowed mode
F4	All	Open/Close Control Panel display
F5	All	Toggle between new display rendering (NTSC accurate) and old display rendering
Ctrl + F5	All	Toggle between linear interpolation display rendering (slight blurring) and nearest neighbor display rendering (sharper)
F6	All	Toggle between Joystick, Joyport, Mouse-emulated Joystick modes
F9	All	Increase speed - 1MHz, 2.8MHz, 7.1MHz, 14.3MHz, and Ludicrous Speed
Shift - F9	All	Decrease speed
Ctrl + F12	MacOS,Windows	Reset
Ctrl + BREAK	Linux	Reset (sometimes, this key is labelled Pause)
