I'd like to never need to reach for a mouse or trackpad.
Right now I spend most of the day mouse free. Alas, I occasionally must reach for a mouse or trackpad. It can really derail a good day.
What is the most efficient method of last resort for "clicking" those elements that have no hotkey, that I can't get any program to provide a keyboard hint for, and that can't be tabbed to?
My expectation is that the answers will be methods to move the mouse cursor and click via keyboard (like mousekeys) but any solution is applicable if it allows a keyboard to do anything a mouse can do.
Update Here's a very specific example of something that I don't know how to control by keyboard. In Firefox I'm unable to start this video: http://vimcasts.org/episodes/comparing-buffers-with-vimdiff/
This specific example isn't too important, the point is that even with tools like Shortcat and Vimperator, sometimes hinting isn't provided. Video controls are a good example of something challenging. (Vimperator sometimes works for video controls, sometimes doesn't.) Maybe there's a better way to get hints for these?
