My cheap Wacom pen mod, step by step.
1. Lose the plastic rocker that provides right and middle mouse clicking on a Wacom pen.
2. Realize it was vacuumed up by the cleaners over the weekend.
3. Steel yourself for the process of making an impromptu rocker.
4. Bend a small piece of plastic into a U shape that contacts the piezo-electric buttons in the pen shaft.
5. Loosely tape it to the pen.
6. Curse every once in a while when it doesn’t accept the clicks.
And here’s a crappy pic of the results.
