Drats. I forgot that both the shift and control keys are already used for changing the way text copying works. The shift key allows you to copy a wrapped line as multiple lines, while the control key allows you to include control codes with the copied line.

The only other available key is the alt key, however that is not practical because of the way it interacts with menubars, shortcuts, and other features.

If anyone can think of another viable method, I am all ears.
