I've been having fun with keyboard navigation, since my track pad quit working. I'd never bothered to learn all the keys until now, but it turns out the support is quite good and I'm not sure I don't like it better this way.
The one major thing that doesn't seem to work as advertised is the key, supposed to get access to the Deskbar but I don't see anything happening. Keymap preferences show that it really does seem to be mapped. Does it work for anyone else? Is it possibly more subtle than I realize, and the Deskbar menus would spring open if I only knew what to do next?
Right now I have a Terminal window on startup, so I can invoke things from the command line, and shutdown etc. I can probably fix the trackpad - I reckon it's a loose connection from when I ripped the laptop apart to change wifi cards. And I have a USB mouse on hand if I need it. Just like being able to stay on the keyboard, and it's a shame the Deskbar is out of commission.
