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"
