Comment:

 Yes, there are several cases where the keyboard is still necessary, though
 the primary use case for Calculate are improved by the recent addition of
 the cusor and back space canvas buttons. The OSK is intended to be raised
 using the OSK Frame Device icon (see the lower right Frame area). This was
 intended as the fallback for all cases not covered by the Input Methord
 auto OSK pop-up, unfortunately there is an open bug for that case, where a
 manually raised OSK is not passing on any keyboard events to the
 widgets/activity.

 FWIW: Help and Plot features in Calculate need a better UI, not had time
 to work on these this cycle.
