Lenovo W520 with multiple displays switching active window to other displays with 1 or 2 key being pressed

We have a Lenovo W520 exhibiting an odd behavior-
When the user types a 1, or a 2 using a keyboard (just the top row numbers, not the NumPad) the active window jumps to display 1 or display 2.
This usually stops after a reboot, but then starts up again randomly.
It's like some hot-key is stuck or something.

Its a Windows 7 machine, and has the Display Closed, VGA to a monitor, and a USB J5 External Display adapter to a 2nd active display.

Any ideas what could be causing this and where to disable it?

"USB J5 External Display adapter to a 2nd active display"

Did this come with software?    It sounds like a third party application adding this hot-key functionality.

It also might be that a "FN" like key (e.g. Scroll Lock) has snapped in, so that pressing 1 and 2 will act like FN-1; still there needs to be some software, 3rd party or by Lenovo, doing that ...

So, the user said they read something about holding both Shift Keys at once, and it will disable that 'hotkey' feature. I couldn't find exactly what they said they did, but they claim it worked.
This would mean that they were enabling filterkeys and not noticing it. And I'm not sure how filter keys could cause the screens to hop.

User found the fix was holding both Shift keys at once. Looks like this might disable FilterKeys which they somehow must have enabled and didn't realize. Multiple times.
