Field input of MAC address: filtered and nice to look

Your solution, ahimè, is getting close to the same size of my original one, that used a reapet loop. May be faster tough.

I am a little ahead of you, in that mine can handle single letter adjustments. Neither can handle multi-letter.

Yet.

Question, why do you hide the input field?

I don't.
The fld "LabelHide" is a place holder, behind the real field, that shows to the user an example of the Mac.
I should have removed any reference to it.
