          Different focus policies:
          <ul>

          <li>ClickToFocus - Clicking into a window activates it. This is
          also the default.

          <li>FocusFollowsMouse - Moving the mouse pointer actively onto a
          normal window activates it. For convenience, the desktop and
          windows on the dock are excluded. They require clicking.

          <li>FocusUnderMouse - The window that happens to be under the
          mouse pointer becomes active. The invariant is: no window can
          have focus that is not under the mouse. This also means that
          Alt-Tab won't work properly and popup dialogs are usually
          unsable with the keyboard. Note that the desktop and windows on
          the dock are excluded for convenience. They get focus only when
          clicking on it.

          <li>FocusStrictlyUnderMouse - this is even worse than
          FocusUnderMouse. Only the window under the mouse pointer is
          active. If the mouse points nowhere, nothing has the focus. If
          the mouse points onto the desktop, the desktop has focus. The
          same holds for windows on the dock.

          Note that FocusUnderMouse and FocusStrictlyUnderMouse are not
          particulary useful. They are only provided for old-fashined
          die-hard UNIX people ;-)

           to. The order automatically adjusts to the most recently used
           windows. Note that KDE style does not work with the
           FocusUnderMouse and FocusStrictlyUnderMouse focus
           policies. Choose ClickToFocus or FocusFollowsMouse instead.

           <li> CDE - the old-fashion CDE style. Alt-Tab cycles between
           the windows in static order. The current window gets raised,
           the previous window gets lowered.
