Textbox Backspace Button

Trying to make a touch button that simulates backspace in a textbox.

Is there a way to use the mid() and len() functions to do this?

like take the middle of the string from start to length - 1 or something and set that as the text ? Am I on the right track here ?

Thanks

Edit: Solved myself by using a family called TextBoxez and doing

on touch, if textbox has focus

set text to mid(TxtBoxes.Text , 0, (len(TxtBoxes.Text ) - 1))

That's the way I used too, I made that question some time ago..
