Powerpoint opens when I hit 1...

I promise Im proficient in Excel but I cannot figure this issue out. When in excel and I press 1 on the far right number pad, Powerpoint opens. This doesn't happen in any other program aside from excel. Any thoughts?

mapped OnKey from your own add-ins?, any key mapping software on your system, does it happen if you open in safe mode, what add-ins do you load with excel
