May 16, 2010 · Left shift key inserts ± (plus/minus symbol) When I try to use the left shift key and hold it down for more than a half-second or so it will insert the ± symbol. Not being the speediest of typists, this has rendered the key useless (besides being a shortcut for that symbol, of course). This occurs in all profiles.
