I'd like to be a good boy and allow use of the F1-F4, page up, page down, help, and other "special" keys. Am I correct in thinking that I have to:
1. Use SysEnvirons to test for the keyboard in use.
2. Use specific virtual key codes for that keyboard.
It would be nice to hear that there are magic character codes for these keys, so I could avoid this hardware-dependent stuff. But if that's the case, I can't find it in IM or the tech notes.
Thanks.

The function keys all share the same charCode, but the six keys above the arrows all have their own "magic" charCodes. They were chosen to make sense in the ASCII realm of things (delete is $7F). I'm actually surprised to see that it is not documented in Inside Macintosh, but the codes can be determined empirically (they won't change). Of course, some of these charCodes can also be generated with the control key pressed, so using the virtual key codes might not be so bad after all. _emt

While we're on the subject of weird keys and their keycodes, does anyone know how to test for the Reset (triangle) key on the ADB keyboards? IM V lists it as 7F7F, but I don't know how to check for dual key keycodes in the result field.

And here they are, the Empirically Determined Char Codes:
PageUp 0x0B (VT)
PageDwn 0x0C (FF)
Home 0x01 (SOH)
End 0x04 (EOT)
FwdDel 0x7F (DEL)
Sorry, I didn't bother with Help. Does anyone know what VT and SOH are
supposed to stand for?

As for SOH, I have no idea. SOH is "Start Of Header". It's used to start a frame in many synchronous data communications protocols. (SYN, for "SYNchronize", is used to fill idle time on the link. The arrival of a SOH indicates that a frame follows.) --Pete Poorman pwp@shamash.cdc.com

Alex Chaffee left the ASCII codes for several of the special function
keys on the extended keyboard, then asked:
> Does anyone know what VT and SOH are supposed to stand for?
I like these easy questions. VT is Vertical Tab. SOH is Start Of
Header.

Here is a fragment of my personal include file for handling the keyboard.
Remember, the numeric keypad has a key that says "Clear" on it, so it should
be a synonym for Clear on the Edit menu, even though it generates the same
ascii code as the Escape key. The escape key of course, should be a synonym
for <Command>-<period> or, in a dialog, for (Cancel).
/* ascii code definitions returned by macintosh special keys */
#define HOMECHAR 1
#define ENTERCHAR 3
#define ENDCHAR 4
#define HELPCHAR 5
#define BACKSPACECHAR 8
#define PAGEUPCHAR 11
#define PAGEDOWNCHAR 12
#define RETURNCHAR 13
/* ascii code definitions returned by arrow keys */
#define ESCCHAR 27
#define CLEARCHAR 27
#define LEFTCHAR 28
#define RIGHTCHAR 29
#define UPCHAR 30
#define DOWNCHAR 31
#define DELCHAR 127
/*
* clear, escape, and ^[ all generate the same code.
* on the small american adb keyboard, the following keyboard
* numbers apply:
* CLEARCHAR (0x47) in the 2nd byte,
* an escape (0x35).
* an ^[ has 0x21.
*
* LEFTCHAR (0x7B) = ^~()
* RIGHTCHAR (0x7C) = ^ ()
* UPCHAR (0x7D) = ^~()
* DOWNCHAR (0x7E) = ^_ (1B)
*
* With 1 keyboard, the 3rd byte reports "2"
