This BrainBashers safe has a rather unusual control panel.

In order to open the safe you have to press every single button once only, in the correct sequence, ending on the button marked E.

Each button indicates which button to press next, for example, 2U means move up 2 buttons and 3R means move right 3 buttons.

Can you determine which button you must start with?
