I have a user whose Tab key stopped working, but only on its own. That is to say, Ctrl-Tab, Shift-Tab, and Alt-Tab all still work. After swapping with a known-good keyboard, Ctrl doesn't work, and escape opens the start menu (which would indicate that ctrl is stuck down). After a second keyboard swap, with a keyboard that is known-good, tested, and absoutely pristine, he reports that the F key and Ctrl key sometimes do not work, along with a couple other keys.

No accessibility options are active, and the BIOS on all machines in this office are identical. What could possibly be going on here, and what can I do about it?

Are you receiving any errors in Device Manager?

To get to device manager, do the following:
Start->Control Panel->Performance and Maintenance->System->Hardware Tab->Device Manager


Type the following into the run dialog box (Located at: Start->Run)

Let me know if there are any discrepancies.

My mind isn't quite sure what it has bargained for, but my heart is in time with, with the consistency of Your's.

The keyboard driver could be damaged...I would try uninstalling it and then rebooting.
