I work in Excel alot and use control+arrow keys to move around the worksheet.
I have no idea why, but now when I hold down control and hit the arrow key
nothing happens.

Shift+Control+Arrow key still functions just fine, selecting everything to a
gap in the data. Control+(any other key) seems to be working fine.

If I hold down control and then hold down the arrow key for a second or two
it will do what it is supposed to do, but it jumps really quickly like it is
not picking up the initial push of the key, but then starts functioning on
the repeat.

Any help would be appreciated
