I'm not sure where to post this, so I figured this place might get the best eyeballs.
I ran into a really bizarre situation this morning. If I could figure it out, it could become the basis of a neat practical joke, but I have no idea what happened. I was in MS Outlook typing an email, when the K key suddenly stopped working. I don't know that I did anything, but I certainly might have hit some kind of odd key combination. At first, I thought it was the batteries in my wireless keyboard going dead, but the wireless keyboard was sending keys to a laptop, so I tried the laptop keyboard and the K key wasn't working there, either.
I then tried the other keys on the keyboard. Most were working normally, except that the X key would produce some three digit key code, possibly the code for the last key pressed prior to the X. The backspace was not deleting the last character, either, but was deleting the last row of text, or the last sentence (I didn't study the behavior enough to determine which it was). Those were the only three keys that appeared to be acting different.
I then opened up NotePad, where all the keys worked normally. I followed that by opening IE and trying a Google search. Once again, all the keys were normal.
One other thing that I noted was that when I pressed the K key, it isn't the case that nothing was happening. The cursor briefly turned into the wait cursor, then reverted back to normal. This suggests that the K key was launching a process that took significant time, though less than a second, and that whatever the process was, it had no visible result.
Finally, I closed Outlook, then opened it again, and all was back to normal.
So the question is: What did I hit, and what was happening?
