> "Indeed, for random access on screen, there is no better alternative than the mouse or trackpoint"
There should be. Touchscreen. Eye tracking. With a mouse I have to go via a silly walk[1] moving my arm and scraping a chunk of plastic over a desk as a proxy for scraping a mouse pointer over the screen. With a keyboard I have to invent a magical incantation of button presses to poke the state machine and make the cursor do a silly walk over the lines/rows/words/brackets/search term/etc. from where it is to where I want it to be. Why can't I look and "go there" directly without either silly walk?
Good point, touchscreen is even faster. Eye tracking may be hard to make work properly (false positives, false negatives, invalid actions...), but would indeed be the fastest.
