If you were expecting an entry about a singer, or a female pet or something, you'll be disappointed. I've been having problems with the L and U keys on my (fancy, wireless) keyboard. Turns out the keys can be popped off; after a few minutes fiddling with the pseudo-rubber doings inside, and performing a transplant between L and Esc, all keys now work fine you can probably guess from the fact that I've typed this.
