A scan code is a two-part or four-part hexadecimal code associated with a keystroke (so called because it comes from scanning the keyboard).

To determine the standardized Business Rules scancodes, run the following program:

10 LET X$ = KSTAT$(1)
20 PRINT UNHEX$(X$)
30 GOTO 10

Each time you press a key, the scancode for that key is displayed.

Here are a few of the Scan codes:

Key Scan Code
Tab 09
Shift+Tab 07
Down Arrow 0A
Up Arrow 0B
Left Arrow 0E
Right Arrow 0C
F7 0700
Shift+F7 1100
Alt+Down Arrow E300

Here's a complete list:
