2.0.22b: Fixed invisible overflow menu items

Pasting real scalars now allows trailing characters, so pasting a number with an attached unit, say 50mm, yields the number 50, not the string "50mm".

INPUT now clears message from display before showing the prompt.

ASTO and ARCL showed the wrong menu in certain circumstances.

Up-arrow and down-arrow didn't work in some command entry scenarios.

While entering a numeric LBL, couldn't switch to ALPHA mode.

OFF now turns off "continuous on" mode.
