Revert removal of fake editing for numeric input

Revert changes from 785159e6e4dfc5c010baab626667132020e1ddc7
but keep 'ifdef'.

@mont29 maintains this area and prefers to keep existing logic.
Note that there was misunderstanding that '*' was intended only
to be a backup key for '=' for keyboards which require holding a
modifier.
