My forward slash key is misbehaving

I was doing some Java programming in Eclipse, and I wanted to type a comment for my code. Simple enough. Just type two forward slashes, followed by the actual comment.

Alas, my keyboard was not cooperating. When I typed a forward slash, I got an "e" with an accent above it. In the spirit of looking for my misplaced keys in the same place I've looked several times already, I kept typing the forward slash, somehow expecting it to magically fix itself. It did not.

So, time to ask my technical expert (Google). After a couple of attempts, I found this post that told me how to fix the problem.

If this happens to you, just press and hold the left Ctrl and left Shift keys simultaneously for about two to four seconds. That should fix it.

Time to get back to writing code...
