But don’t fall for the trap of thinking that just because you’re doing something with a keyboard rather than a mouse, it’s more efficient. Very often, a keyboard /feels/ faster, but the satisfying click of a bunch of keys is not necessarily faster than just mousing, especially given that you usually have to move your hand from the mouse to the keyboard. For some things, like copying and pasting, the keyboard commands are certainly faster; but this in most instances. I direct you to

If you really want to get fast, I suggest you install and start using Cocoa Gestures (http://www.bitart.com/CocoaGestures.html). When I used a Mac with a discrete mouse (I have a Powerbook now, and just use the trackpad) I was able to save huge time with sensible gesture actions.
