Control + Delete

[pooper200000]

Usually control + delete (in a word document or on these forums) causes for the last word you typed to be deleted. On graal however if you open a pm and press the backspace (what I am calling the delete key) while pressing the control key a wierd faintly lit square appears. It is small and takes a second to notice. I would like this to be fixed because I avidly use this in game or on the forums.
