I HATE SHORTCUT KEYS!!

i had a blog all written up, venting about something i am rather pissed off about, and then i hit the wrong key and my computer whent back a page! is there a way to fucking disable that?! cuz when i come on here to vent usually i am close to my wits end and just want to get it all out in a blog, but when i come on here, type it up, and see it get deleted like that all it does is get me all keyed up and when i've had two anxiety attacks in the past week that is not a good thing! HOW DO I FUCKING DISABLE IT SO IT WONT TAKE ME BACK A PAGE FOR PRESSING THE WRONG KEY?! Cause with today's technlolgy there *has* to be a way.

Keep running,
