xev and xmodmap output

Reproduction Steps

Remap Caps_Lock to Escape

xmodmap -e "clear lock"
xmodmap -e "keycode 66 = Escape NoSymbol Escape NoSymbol Escape"

Add this to your rc.xml config file.

...
<keybind key="A-S-w" chroot="true">
            <keybind key="Escape"><action name="BreakChroot"/></keybind>
</keybind>
...


When in chroot mode regular escape works but the caps lock escape does not.
