Is it a number? You could have a standard laptop keyboard and turned on numlock but I can't write much more because vital information is missing. Just in case, a google for you.
i accidentally hit some combination of keys near bottom right of my keyboard and now certain letters won't type properly such as capital h or b and some symbols such as number sign and dollar sign won't type at all. also the shift key doesn't do what it used to do in my drawing program - coreldraw x5. I am running windows 7 home premium. i just want the keyboard restored to the way it was before - the default setting without all this goofiness - anybody know how to do that?
