Here ' s what I see basically every sound editor in hollywood using I use this tooBottom left Regular ClickBottom Right F 6 Trim ToolUpper Left F 7 Insertion PointSelector toolUpper Right F 8 Hand ToolI use USB Overdrive I very much miss Mouseworks , which was superior to Trackball Works in just about every way . so that I can have profiles for different programs , instead of just one profile like trackballworks mouseworks had multiple profiles . The only thing I don ' t have is the ' chording ' two buttons at once . Anyway , get fast with that key combo and you ' ll shave TONS of time off of editing compared to the super tool . Learn the keyboardfocus keys , too I zoom in with rt , fades are on dfg , head tail trims on as , etc . You rarely have to have your hand leave your mouse .
