This might be a silly question, but coming from using a magic mouse on a mac, AE CC2014, I migrated to using a Wacom tablet. One thing I really miss is the ability with my mouse to swipe my finger left and right on the back of the mouse to make the timeline go left and right. I would like to find if there are any hotkeys to do this so I can program the keystrokes into my tablet. I've looked through the AE keyboard shortcuts reference online, but I'm not sure I even know what this is called, so I haven't had any luck locating hotkeys for that. Any help would be appreciated. Thanks!
