Dear Ctrl-Z (aka Command-Z or Apple-Z on a mac),
Thanks for saving my ass on so many occasions, such as when I deleted an entire just-written article last week. I just pushed those your lovely keys and back it came, preventing me from having to work late and miss Happy Hour. You are the hottest thing that's been created since QWERTY hooked up with personal computational power almost three decades ago, and you can "Undo" me anytime.
Wishing for a quickie with a quick key,
