+ * ++roman: The following changes were applied manually:
+ *
+ *  - The Alt (= Meta) key works in combination with Shift and
+ *    Control, e.g. Alt+Shift+a sends Meta-A (0xc1), Alt+Control+A sends
+ *    Meta-Ctrl-A (0x81) ...
+ *
+ *  - The parentheses on the keypad send '(' and ')' with all
+ *    modifiers (as would do e.g. keypad '+'), but they cannot be used as
+ *    application keys (i.e. sending Esc O c).
+ *
+ *  - HELP and UNDO are mapped to be F21 and F24, resp, that send the
+ *    codes "\E[M" and "\E[P". (This is better than the old mapping to
+ *    F11 and F12, because these codes are on Shift+F1/2 anyway.) This
+ *    way, applications that allow their own keyboard mappings
+ *    (e.g. tcsh, X Windows) can be configured to use them in the way
+ *    the label suggests (providing help or undoing).
+ *
+ *  - Console switching is done with Alt+Fx (consoles 1..10) and
+ *    Shift+Alt+Fx (consoles 11..20).
+ *
+ *  - The misc. special function implemented in the kernel are mapped
+ *    to the following key combinations:
+ *
+ *      ClrHome          -> Home/Find
+ *      Shift + ClrHome  -> End/Select
+ *      Shift + Up       -> Page Up
+ *      Shift + Down     -> Page Down
+ *      Alt + Help       -> show system status
+ *      Shift + Help     -> show memory info
+ *      Ctrl + Help      -> show registers
+ *      Ctrl + Alt + Del -> Reboot
+ *      Alt + Undo       -> switch to last console
+ *      Shift + Undo     -> send interrupt
+ *      Alt + Insert     -> stop/start output (same as ^S/^Q)
+ *      Alt + Up         -> Scroll back console (if implemented)
+ *      Alt + Down       -> Scroll forward console (if implemented)
+ *      Alt + CapsLock   -> NumLock
+ *
+ * ++Andreas:

+ *  - Undo mapped to K_UNDO (= K_F246)
+ *  - Keypad Left/Right Parenthesis mapped to new K_PPAREN[LR]

+ * bytes (that are usually mouse bytes) than to misinterpret them. Therefor I
+ * introduced the RESYNC state for IKBD data. In this state, the bytes up to
+ * one that really looks like a key event (0x04..0xf2) or the start of a mouse
+ * packet (0xf8..0xfb) are thrown away, but at most 2 bytes. This at least
+ * speeds up the resynchronization of the event structure, even if maybe a
+ * mouse movement is lost. However, nothing is perfect. For bytes 0x01..0x03,
+ * it's really hard to decide whether they're mouse or keyboard bytes. Since
+ * overruns usually occur when moving the Atari mouse rapidly, they're seen as
+ * mouse bytes here. If this is wrong, only a make code of the keyboard gets
+ * lost, which isn't too bad. Loosing a break code would be disastrous,
