Sometimes when I want to delete a line of text very quickly I do this:
I hold the shift key and press the arrow up key to select the line above and then I press backspace. But occasionally I press all three keys at the same time which deletes the line too but creates a hidden control character with the value 08: the value for the backspace control character.
This can be pretty annoying e.g. if you are writing code and you can't figure out what causes the parse error.
Am I the only one who struggles with this from time to time? Is it possible to change this behavior?
