How to turn off tab + space submitting a reply?

Nope, definitely not. My hand was not even close to the Enter key. In fact it happened when I hit some keys with either cmd, option, or control (or a combination of any of the meta keys) with my left hand. My right hand was not even on the keyboard.

I believe you that control+enter is one shortcut that triggers that behavior, but it’s for sure not the only one.

I’m not.

So what does that mean? I can’t turn them off?

P.S.: I forgot to mention: thanks for the reply.
