Mapping Caps Lock to Esc in TTY

Hello to everyone I was wondering if there was any kind of setting which would allow me to map CAPS LOCK to an additional ESC.

I do this with setxkbmap in X sessions, but I would like to have something that would set that also in TTY.
Anyone aware of such thing?

netbsdnoob Hello to everyone I was wondering if there was any kind of setting which would allow me to map CAPS LOCK to an additional ESC.

PS/2 or USB keyboard? (Or some other exotic type?) And, what country variant: US, UK, DE, ...?

For a single PS/2 (also XT, AT) US keyboard, put this in /etc/wscons.conf

mapfile=/etc/keymap-ps2.txt

And in /etc/keymap-ps2.txt mapfile:

keycode 58 = Escape

For a system with just a US USB keyboard, create a mapfile containing:

keycode 57 = Escape

For anything else, refer to:

PS/2 scancodes: sys/dev/pckbport/wskbdmap_mfii.c
USB scancodes: sys/dev/hid/hidkbdmap.c
Symbol names: sys/dev/wscons/wsksymdef.h

netbsdnoob how do i create a mapfile?

Use a text editor? (I've already given you the mapfile, above, mate)

netbsdnoob i would also like ( ) to [ ] swap them.

For a US PS/2 keyboard, add this to the mapfile:

keycode 10 = 9 bracketleft
keycode 11 = 0 bracketright 
keycode 26 = parenleft braceleft
keycode 27 = parenright braceright

netbsdnoob Is there any documentation you can refer ?

Also already given. See also wsconsctl(8), wskbd(4) and wscons.cfg(5)
