-/* DEFINITIONS:
- Return from SLANG: KeyCode: 0xaaaabbcc
-
- where: aaaa = Flags
- bb = Scan code
- cc = ASCII-code (if available)
-
- if no flags (CTRL and ALT) is set, cc will be returned.
- If CTRL is pressed, cc is already the XCTRL(code).
- case cc is:
- 0xE0: The scan code will be used for the following keys:
- Insert: 0x52, DEL: 0x53,
- Page_Up: 0x49, Page_Down: 0x51,
- Pos1: 0x47, Ende: 0x4F,
- Up: 0x48, Down: 0x50,
- Left: 0x4B, Right: 0x4D,
-
- 0x00: The function keys are defined as:
- F1: 3b00, F2: 3c00 ... F10: 4400, F11: 8500, F12: 8600.
- With ALT-bit set:
- ALT(F1): 6800, 6900,... ALT(F10): 7100, ALT(F11): 8b00
- ALT(F12): 8c00
-
- Mapping for ALT(key_code):
- For Mapping with normal keys, only the scan code can be
- used. (see struct ALT_table)
-
- Special keys:
- ENTER (number block): 0xaaaaE00D
- + (number block): 0xaaaa4E2B Normal: 1B2B
- - (number block): 0xaaaa4A2D Normal: 352D
- * (number block): 0xaaaa372A Normal: 1B2A
