Numeric Input: remove fake-editing option

Numeric input allowed mix of editing and hotkeys which were interpreted
as modifiers instead of using as numeric input.

This meant entering '1.0*3' needed to be typed as '1.0**3'
('*' to activate, and again to multiply).

Pressing '/' gave the reciprocal of the current number
which could be useful.

Test removing this feature, so only full numeric input is supported.
