Meanwhile I though of a different approach to my particular problem.

I can create two menu configuration options, one without changing
anything at all to the append line.
The other one, when selected, should behave like TAB was pressed, thus
allowing the user to type something into the line.

With a strict instruction set, one could more or less ensure that the
users type just numbers, or else this installation is voided.

Being so, how can I force the user into edit mode after a particular
option is selected?
