Several times over the last couple weeks, I type up a very well thought out response on Facebook in political conversations with friends. An hour or two into my work, I hit backspace with the intent of editing what I wrote (maybe after I scrolled or something, so maybe I unintentionally took the edit window out of focus). The navigator takes me back a page and I lose my two hours of work. Infuriating! Shortcuts with the ability to wipe out two hours of works should be disable-able. Not only that, I feel that is an unsafe shortcut for this very reason, and would have added a SHIFT modifier key or something like that. I think I invented a cool word: disable-able.
