I'm having a very odd problem where the keys F, V and ⌫ (backspace) stop working for no apparent reason!
Then the problem seems to fix itself some time later, to reappear afterwards.
What's causing this and how to avoid it? It's getting really annoying. And I don't understand why only those 3 keys fail to work, the rest of the keyboard works just fine.
I don't think it's really a hardware issue. I'm on High Sierra 10.13.2. I use Karabiner-Elements to program some keys and at first I thought it could be the culprit (even though I have used it for a long time with no issues), but the problem persists even after quitting that app.
