Great thread, one of those things good to revisit' every once in a while.

I"m pretty sure default is CTRL+arrow key, no? I smack those things constantly when I'm editing. I think if a better way came along I'd never be able to retrain myself.
My method generally as well.. now if I could have a wish it would be to tailor' the action a bit - Seems it's speed starts out ok, but it's ramp up' speed is so steep. I'm always playing this 'timing thing- trying to get to and from the target zoom, say '75%' zoomed in or back to '25%' w/o overshooting.
