It does! Just instead of typing in a number to activate distance constraint, go to the "d" (for distance) box in the bottom toolbar and click on it and enter a number with the little pop-up panel. That will work without ever needing to touch the keyboard.

But actually, I guess you do need to use the keyboard for one thing I mentioned above, the "rx,y" relative coordinate method. There isn't currently any non-keyboard replacement for typing in the initial "r" to indicate relative coordinates.
