How do I disable the Caps Lock key? Updated: 04/07/01

To disable the "placement challenged" Caps Lock key on the ITF keyboard,
use an xmodmap script:

Add the below lines to your ~/.dt/sessions/sessionetc:

/usr/bin/X11/xmodmap - <<'EoF'
clear lock
keycode 55 = Control_L
keycode 86 = Caps_Lock
keycode 39 = grave asciitilde guillemotleft guillemotright
keycode 71 = Escape
add Lock = Caps_Lock
add Control = Control_L

This works until logout/login, when Caps Lock toggles the control
even though 'xmodmap -pm' shows that Lock has no assignments. You have
restart the X server to reset completely, which can be automated by
uncommenting the line:

Dtlogin*terminateServer: True

in the file {/usr,/etc}/dt/config/Xconfig.
