I purchased a used Aspire One from an Asian gent. He advised me that it has a multi-keyboard of some kind. I must have touched one of the controls and now certain keys produce the wrong choice. For example, when I wish to hit the <L> key the number <3> appears (both the K and the 3 are imprinted on the key). If I hit the <K> key, I get the number <2> The shift locks do not affect these keys. Obviously, somewhere on the keyboard, there is a key or a combination that will undo the problem that's been created. Thanks for any help.
