I got myself a new PC a couple of weeks ago and I've got a little problem. On the keyboard '4' key, I have got a '$' sign on shift and an E(Euro) sign to the right of the '4'. As you may have noticed, I don't know how to access it. I've tried using 'Ctrl', 'Caps lock' and 'Num lock' all to no avail. How do I get at it?
