Try vimium, which is probably fast (although I usually still prefer the touchpad). This is what it looks like: https://user-images.githubusercontent.com/2781117/28320939-f...

It's one keypress to get the hints, then usually two to select the element, whereas tab-navigation is 1/4 the number of elements on the page (if you do shift+tab whenever it's shorter) and this Manhattan-style keyboard navigation is 2 x sqrt(# elements), if I'm not mistaken.

Here's what I thought just reading the title: press a key, and the elements are spacially mapped onto all keyboard keys (except ESC). Then, hit the key in the general vicinity. If there's too much and you are likely to miss, zoom into the specific area and repeat.

That's really equivalent to the vimium method, but a bit more visually intuitive.
