urxvt fullscreen (or anything else), openbox

~/bin/fullscreen is a script like

#!/bin/bash
# toggle fullscreen, usefull for urxvt. Possibly can be maped to some key in openbox rc.xml.

command -v wmctrl >/dev/null 2>&1 || { >&2 echo "I need wmctrl installed." ; exit 1; }

wmctrl -r :ACTIVE: -b toggle,fullscreen

and in ~/.config/openbox/rc.xml an entrie like

<!-- fullscreen toggle script -->
    <keybind key="W-F11">
      <action name="Execute">
         <command>fullscreen</command>
      </action>
    </keybind>

will make urxvt toggle into fullscreen mode (or any other app I assume). W-F11 stands for ‘super + F11’ key combo. Super is sometimes known as Winkey.
