"keynav is geared towards selecting a piece of the screen very quickly."

"You select a piece of the screen. The screen is initially wholely selected. One move will cut that region by half. A move is a direction: up, down, left, and right.

Umm, but this is not quite what I want. Because, you are not going to click on OK using that, right? You can stick to keyboard by focusing the window and then pressing Alt-o. So what I'would like to see implemented in xmonad would be to use say Mod+Numeric 9 to select whatever window sits in the upper right corner, Mod+Numeric 7 for left corner, Mod+numeric 5 for most central window, mod+numeric 6, for right central window, etc. When you have too many windows, this is often ambigous so you select one by some sort of heuristics... But even on my 30" screen, I rarely have more than 4-6 windows on any given desktop... The idea is that often you want to focus "that window up there" rather than window #3, so some sort of graphical intuition from buttons will be helpful (that is the entire point of mouse after all)... anze
