I've set the environment variable HOUDINI_MMB_PAN = 0, so i can more easily use my wacom bamboo with Houdini.

One thing i really miss when using my tablet is changing parameters/values, which you normally do with de MMB.

Is there a shortcut or something that makes me do this with my pen?

I usually set that on my pen…top button = middle click.
