Select nearest by keyboard

[phavx]

Hi, just found this in Gentoo's portage, tried it and like it very much(danke dafür :)

One thing I would love is to be able to select an entry via keyboard. For example, have a marker at the top, rotate the ring and on keypress, execute what is nearest to the marker. Alternatively (or and) make the same possible, but in any direction, so press (for example) the right key to launch whatever is at the 3 o'clock position.
