Keyboard layout

The keyboard layout closely resembles that of a real C64. The individual rows of the keyboard are mapped as follows (american keyboard):

<- 1 2 3 4 5 6 7 8 9 0 + -
    Q W E R T Y U I O P @ *
    A S D F G H J K L : ;
     Z X C V B N M , . /

In addition, the following keys are used:

 Esc        - RUN/STOP
 Backspace  - INS/DEL
 Return     - RETURN
 Enter      - RETURN
 Shift keys - SHIFT
 Caps lock  - SHIFT LOCK
 F1-F8      - F1-F8

Special keys under BeOS:

 \          - ^
 Insert     - Shift-INS/DEL
 Delete     - INS/DEL
 Home       - CLR/HOME
 End        - £
 Page Up    - £
 Page Down  - =
 Menu Keys  - C=
 Ctrl Left  - CTRL
 Ctrl Right - C=
 F11        - RESTORE
 F12        - C64 Reset

Special keys under Unix:

 \          - ^
 Insert     - Shift-INS/DEL
 Delete     - INS/DEL
 Home       - CLR/HOME
 End        - £
 Page Up    - ^
 Page Down  - =
 Alt Keys   - C=
 Ctrl Left  - CTRL
 Ctrl Right - C=
 F9         - Start SAM
 F10        - Quit Frodo
 F11        - RESTORE
 F12        - C64 Reset

Special keys under AmigaOS:

 \          - £
 Delete     - CLR/HOME
 ( (keypad) - ^
 ) (keypad) - =
 Alt Keys   - C=
 Ctrl       - CTRL
 F9         - RESTORE
 F10        - C64 Reset

Special keys under RISC OS:

 F5         - Toggle sound emulation mode
 F6         - Enter SAM
 F7         - RESTORE
 F8         - Reset
 Copy       - Toggle pause
 PageUp     - Increase SkipFrames
 PageDown   - Decrease SkipFrames
 num/       - Toggle 1541 emulation mode
 num*       - Toggle speed limiter
 num+/-     - +/-
 Alt        - CBM
 ScrollLock - On: force single tasking, else multitasking

Apart from that the function keys are mapped differently under RISC OS. (F1,F2,F3,F4) maps to the C64's (F1,F3,F5,F7), you get (F2,F4,F6,F8) by pressing shift like on a real C64.

So the famous key combination RUN/STOP-RESTORE must be typed as Esc-F11 (Esc-F9 under AmigaOS). But you don't have to thrash the F11 key the same way as the RESTORE key on the original C64. :-)

The cursor (arrow) keys work as expected. I.e. "cursor up" corresponds to "Shift-cursor down" on the C64. The same applies to the function keys F2, F4, F6 and F8. The numerical keypad emulates a joystick in port 1 or 2, depending on the state of the Num Lock (Num Lock off: port 2, Num Lock on: port 1):

   7    8    9
        ^
        |
   4    5    6
  <-- Fire  -->
        |
        v
   1    2    3

   0
 Fire

Keyboard joysticks are handled differently under RISC OS:

NumLock on: only joystick 1 active, mapped to port 2. NumLock off: both joysticks active, 1 mapped to port 1, 2 mapped to port 2.
Joystick keys can be defined freely. Defaults are: joystick 1: (1 2 3 . enter) on the numerical keypad, joystick 2: (z x f c g).

The '+' and '-' keys on the numerical keypad increase and decrease the "Draw every n-th frame" setting on the fly. The '*' on the numerical keypad toggles the "Limit Speed" option. The '/' on the numerical keypad toggles the processor-level 1541 emulation.
