Things that make you go GGGRRRRRR!!!!

I have a laptop. I haven't figured out what button it is that I randomly push yet, but it's my enemy. I had a very long, boring, informative post almost complete on how much I love not drinking caffeine and somehow I pushed "the button" and BAM - it's gone!!! The whole post. I went to edit my post hoping that it hadn't auto-saved the deleted post, but it had. Now you, my loyal reader, will have to wait for another day. I know you'll be waiting on pins and needles, but I just can't subject myself to another 45 minutes of rewriting it. Where the heck is that button???
