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