"the focus may have moved to or from the frame." is how it usually
written in X documentation, and I think that is a little clearer.

Also, why not add the following as well:

  when no window manager is running, or inside child frames, the focus
  can also be set "implicitly" by the mouse pointer entering a frame.

WDYT?
