Arrow keys intermittently doubling

Yes, it appears that problem does occur with the backspace key as well. It looks like I hadn't noticed that.

I haven't determined yet if the time interval between key presses seems to matter, but in my testing I see the behavior fairly often when tapping the keys at roughly 0.5-second intervals.

Perhaps certain key contacts might be dirty, corroded or worn causing noisy operation which results in a longer key [bounce] period than the calculator software can handle.

Maybe a peek inside might reveal the culprit.
