 Posted: Thu Jan 29, 2009 10:37 am Post subject: TIP: move Capslock on console to Shift-ShiftLock key |
 |
|
I never use CapsLock ! Never ? Yes I very often 'use' it when I accidentally press the ShiftLock key and write things like EMERGE __SYNC _UdnATV WORLD.
So I was looking for a way to disable the ShiftLock key while working on console. In addition, just in case someone might actually want to use CapsLock, I wanted to make it possible to use Shift - ShiftLock to activate and deactivate CapsLock.
Note: in the above, I use ShiftLock to mean the key, and CapsLock to mean the functionality.
It turned out I had to take some time and attentively read man loadkeys and man keymaps. I will not reiterate the contents here, but just explain my conclusions
First make sure you know the keycode from the ShiftLock key by running (from a console, not a terminal emulator under X):
and press the ShiftLock key. you'll see something like
| Quote: | keycode 58 press
keycode 58 release |
Wait for 10 seconds to return to the prompt.
using loadkeys, we can now easily change the key assignment
this can be done manually (as root) from the command line)
| Quote: | loadkeys >> EOF
plain keycode 58 = VoidSymbol
shift keycode 58 = Caps_Lock
EOF
|
However, a cleaner way is to create a keymap that can be loaded by /etc/init.d/keymaps
| Quote: | cd /usr/share/keymaps/i386/include # where the keymaps for my pc are stored
# create the keymap file
cat << EOF >> shiftcaps.map
keycode 58 = VoidSymbol
shift keycode 58 = Caps_Lock
EOF
gzip shiftcaps.map # compress it into shiftcaps.map.gz
|
Now edit the key EXTENDED_KEYMAPS in /etc/conf.d/keymaps
I have
| Quote: | EXTENDED_KEYMAPS="backspace keypad euro2 shiftcaps"
|
The last word ('shiftcaps', not 'shiftcaps.map.gz') makes loadkeys load the new keymap when you run
| Quote: | | /etc/init.d/keymaps restart |

javeree,
Thank you very much. This could be the next great advance in computing.
I am having trouble finding the showkeys command. Do you know what package contains it?
| Code: | | equery belongs showkeys |

Found it... It is not "showkeys", but "showkey".
| Code: |
zippy logrotate.d # equery belongs showkey
[ Searching for file(s) showkey in *... ]
sys-apps/kbd-1.13-r1 (/usr/bin/showkey)

great tip javeree!
i changed capslock to esc like i do under x.. it makes using vim so much nicer :)
| Code: |
keycode 58 = Escape
alt keycode 58 = Meta_Escape
shift alt keycode 58 = Meta_Escape
altgr alt keycode 58 = Meta_Escape
control alt keycode 58 = Meta_Escape
shift control alt keycode 58 = Meta_Escape
altgr control alt keycode 58 = Meta_Escape

Wow, thanks... I've always edited /usr/share/keymaps/i386/qwerty/us.map.gz directly to make my customizations, and for some reason I never even noticed the EXTENDED_KEYMAPS variable before... and I've been editing the keymaps file for years! Am I blind?
Now I can put all kinds of crazy custom extensions in there without editing the default keymap file. Fantastic. |

Thanks for this, working good, but one question @sleipner:
When I include | Code: | shift control alt keycode 58 = Meta_Escape
altgr control alt keycode 58 = Meta_Escape |
I get an error stating | Code: | loadkeys: /usr/share/keymaps/i386/include/ph_esc-lock.map.gz:7: adding map 13 violates explicit keymaps line
* ERROR: keymaps failed to start |
Any hint on that? My default keymap is | Code: | | keymap="de-latin1-nodeadkeys" |
Edit, under X, is there a better way as using xmodmap? |

my keymap is fi-latin9 so that might do the difference.
this should give you correct keymap for escape, just copy needed lines to your keymap file and replace keycodes
| Code: |
dumpkeys|grep Escape

Thanks, for the reference, this is my output | dumpkeys | grep -i escape wrote: | keycode 1 = Escape Escape
alt keycode 1 = Meta_Escape
shift alt keycode 1 = Meta_Escape
keycode 4 = three section threesuperior Escape
control alt keycode 4 = Meta_Escape |
