Okay, so we are talking about editing where the control characters
are invisible.

We are also talking about a non novice: ie: someone who understands
what a [RLM] character means and how to insert it.

For this case we may in fact want to have two logical cursor
positions with one physical position.

Being able to hit the arrow key twice at that position would give
this expert user the option of being before or after the invisible

Having to hit the backspace character once for the invisible
character would give them the ability to delete just that character
even if it is invisible.
