I think you're talking about accidentally hitting the Help key -- which is right next to the backspace key on an extended keyboard, which used to drive me nuts, too.
The solution is to remap the Help key to something else in the Menus section of BBEdit's Preferences. I set mine to Window > Bring All to Front, which is pretty innocuous, and doesn't affect anything I've typed. -- You received this message because you are subscribed to the "BBEdit Talk" discussion group on Google Groups.
