selection: update selection on key-presses

Commit 2cea115ddb7528d9e6dd1bf918ebf5c670b82479 "fixed" the selection
by hooking into mouseRelease events. An unintended consequence was
that scrolling with the cursor keys didn't update the current dive.

Therefore, also hook into the corresponding key-press events.
This is just horrible, but I'm not aware of any possibility to fix
it properly.
