You can set Applescripts that'll let you use your buttons for practically anything, so I'm wondering if there's something that will let me set the left button as the LEFT arrow, and the right as my RIGHT arrow? I'm currently working on a video where I have to draw on top of every frame (rotoscoping), and because I'm mostly just clicking like 50 million times to paint with the brush, and then using my arrows to move between frames, it would be more efficient for me to not have to touch the keyboard period. Can I write something like that in Applescript? Is there a better way to set this up. I don't really have many choices in the mouse setup. I don't know if it has to do with the fact that my mouse is from 2006, or it's just an OS X thing in general.
