I want to assign the middle mouse button to the space key, so I can pan in Photoshop and illustrator without using the keyboard.

I'm sure something like that must exist for Mac OS, but I only find references to the opposite which is making a click with the keyboard.

  • Try Bettertouchtool. have not used it with 3rd party mic, but know there is an option for other mice Would not be surprised if it can do middle buttons.

  • Thanks, in fact I already have BTT installed... but I always thought it was only for the trackpad. D'oh!

  • It worked... but I had to disable Smooth Mouse for it to work. Using Mac OS without smooth mouse is a PITA... so I need another solution for the keystroke.

I found Controller Mate that does exactly what I need, but for some reason it doesn't work in Photoshop or Illustrator. I've tried in other applications and it works...


The bizarre thing is the hand icon appears, but still no pan, even if I have also set the middle mouse button to perform a left mouse click.
