Cursor problem

[TG2G1B]

As of today, my cursor is jumping to top of page in the middle of my entering
numbers into the text. I place it back where it belongs and it jumps again
in the middle of typing?? Any one know what key I may have pushed in error or
solution?

Have you checked to make sure you haven't accidentally turned off Num Lock?

Is it a laptop? The trackpad might be oversensitive: see if there's a
way to turn off the trackpad when a mouse is plugged in.
