Hi again, @Udhy. Unfortunately the issue returned after about 12 hours using the computer, so I'm guessing it's not the NVRAM. I've never had this happen since I have this computer and now it's happened 3 times in 2 days. Somehow I feel like it must be connected to the fact I'm suing the HDMI output for a second display. Although I can't understand why that would happen...

@Udhy It's interesting that I'm having a VERY similar problem - every once in a while (could be after days) my MBP will suddenly act as if the left shift key is stuck in the same way (it's clearly not and it toggles, but inverse to normal). Additionally, the other keys stop working (trackpad/top bar are fine). Reboot, and it's like it never happened. I use a Logitech mouse (via their Unifying receiver) and rarely a keyboard (usually not til this happens) but which is normally off. I suspect it's some driver in the stack that's doing this, but it's so rare I haven't narrowed it down.

NVRAM/PRAM doesn't have anything to do with keyboard issues. Do not copy-paste bullshit here. This is Ask Different, not Apple Support Forum.
