I have a laptop and have managed to press a button on the keyboard (don't ask me which key I mistakenly pressed!) and now my scroll up and down and side to side arrows don't scroll when I press them (for example when I am in excel).  When pressed they open a new folder or something like that.  I have been persevering with tabing along etc, but now it is annoying me and I am sure someone would be able to help to get them back to scrolling?  I am pretty up to speed with computers and this is probably something really simple to fix, but I feel so dumb asking this question
Anyone know how to help me please??
