Subject: [PATCH] selection: forced selection requires keyboard focus

Up the requirements for enabling "forced" selection (that is, allowing
selections even though mouse tracking has been disabled).

* Require keyboard focus (if we don't have it, then the shift-key
  isn't is for us)
* Don't just require shift being pressed, but that all other modifiers
  are *not* pressed.
