I actually like the ctrl+Enter shortcut for sending mail. It's used in a lot of other software too and I automatically try ctrl+Enter when submitting any text.
Thank you for sharing this! I am guessing that they borrowed Outlook shortcut where Ctrl + Enter sends the email.
Try Shift + Enter to start a newline.
I seem to have 5 thumbs, as I often press the wrong key when using different keyboards.
I couldn't agree more. Who needs a shortcut to send an email anyways?
