How to bind actions to Raspberry PI (hot)keys?

I want to define a key for starting the lxterminal on my Raspberry PI.

This is how you can do it:

• Open the LXDE configuration file:
  sudo nano ~/.config/openbox/lxde-rc.xml

• In the <keyboard>(…)</keyboard> section add the following lines of code:
  <keybind key=”F4″>
    <action name=”Execute>
      <command>lxterminal</command>
    </action>
  </keybind>
  <keybind key=”F5″>
    <action name=”Execute>
      <command>gksu /usr/bin/x-terminal-emulator</command>
    </action>
  </keybind>
  

• Reboot the PI:
  sudo shutdown -r now

When it’s back up-and-running, pressing the <F4>-key will launch the LX Terminal and the <F5>-key will launch the Root Terminal.
