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.

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.
