As you may note from this question, I am not a skilled user. I run dual monitors on a dell desktop with windows 7 pro. All was good until recently and now whenever typing if I use the 1 and 2 number keys on qwerty (not number pad) the window I am working in jumps monitors. Apparently I inadvertently activiated some hotkey function, which after a frustrating day of trying to find in a manual and elsewhere, have come up empty. Any clue on how to deactivate this? Thank you.
