#MAKE CAPS LOCK ACT AS ESCAPE IN VT 
#GOPHER://TRIAPUL.CZ 
#PRACTICAL UNIX SURREALISM

Locate the keymap file you are currently using.

	ie: /usr/share/vt/keymaps/us.kbd

Copy the file and rename it to whatever you like.

	# cp /usr/share/vt/keymaps/us.kbd /usr/share/vt/keymaps/custom.kbd

Edit the new file and look for the line containing `clock':

  058   clock  clock  clock  clock  clock  clock  clock  clock   O

Replace the first `clock' with 'esc'

  058   esc  clock  clock  clock  clock  clock  clock  clock   O

Test the new configuration on the fly:

	$ kbdcontrol -l custom.kbd

To load the new keymap on boot, edit /etc/rc.conf and add/change
the keymap variable. This is the name of the keymap file without
the *kbd suffix.

	keymap="custom"

See kbdmap(5) for other key codes.

To still use CAPS LOCK with this configuration, you may toggle it
with CTRL + CAPS LOCK.
