About 9:30 last night, my trusty IBM Model M keyboard started coughing up Questionable Characters. I’m not at all sure why, but I’m guessing its internals got slightly damp during area cleanup. Of course, I have a spare keyboard, but it’s a fairly recent clunker with weird feel and all the lovely Windows buttons I have so far been happy to avoid.
The only liquid near the desk at the time was water. It will dry overnight. I’ll put it back on the desk tomorrow or the next day to see if it has healed itself. (Somehow, this worked once before.)
