1. Exactly - you accelerate your tasks. Your keyboard is not accelerated. Combining keys does not make your keyboard faster; that's like calling shorthand a "pencil accelerator." Really it's a quibble, my problem thanks to a liberal arts education. Your mileage varies, that's fine, don't worry about it.

2. Your orginal post, which raised my question, hailed the benefits of not moving the mouse pointer. But you do move your mouse pointer. As long as your mouse-hand is in action, a pie menu seems a reasonable alternative to getting the other hand involved; thus leaving one hand totally free for vital multitasks: for snacking, for twiddling the remote, for twiddling yourself, etcetera.
