Emails sending instantly with keystroke by accident! What keyboard command does this?!?

@mgmerrill 

Using my comcast/xfinity email account. My mouse is nowhere near the send button when this happens, and I am typing when it happens, so I am certain it is a keyboard shortcut I am triggering my accident. The key, or key combo, is somewhere on left side of my keyboard. This has happened twice, but I can't seem to duplicate it. There is some button over there, or combo, that instantly sends my email. So, out goes a half-written email! No message of any kind precedes the send...whatever keystroke it is just acts immediately. Help! Does anyone know what this could be?? 

Are you logging into the website for composing your emails or are you using an email client?

You got it. I see now it is exactly as you describe. Explains everything. And I agree: I can see why this kind of control can help certain folks in certain needs, but I gotta say it should absolutely be able to be turned off. I have sent a couple emails in really embarrassing fashion; I know the recipient must be going [Edited: "Language"] and there's really no way to explain. I have only been able to say, "sent by mistake" and offer a finished version -- but both times the email has needed a lot of finishing work, and there is nothing I can do right away. Really, really bad.  The only workaround that strikes me as reliable so far is to remove any addressees during my whole composition process, which is a silly pain, especially in cases where I am in a reply/forward mode. I know Xfinity doesn't really pretend to be a pro-level email client, but it has suited my needs...until this. Please, Xfinity, if you are listening, add a disable function to your keyboard stroke shortcuts. Thanks for the help, Bruce.

Hello. It is a standard practice that pressing the tab key moves forward from one element on a Web page to the next element. An element can include a link, a button, check box, edit field for writing text, etc. Shift+tab moves backward, moving in the opposite direction. Pressing the space key on a link or button activates that link or button. This means that if you are focused on the Send button pressing the space key activates that button. This is not a feature specifically to Xfinity Web sites. It is a standard on all Web sites and I've never encountered a Web site that permits the user to disable these keystrokes.

Just to add--------If I have the cursor in the To: field but its empty, and then hit Tab-Spacebar, it opens the address book.  If I do the same thing in the Subject field, it opens a box asking me to insert a subject or send without one.  I'm on a Mac if that makes any difference.

Hi. Generally, pressing the tab key along with the space key isn't a valid keyboard shortcut. You can use keys such as shift, command, etc. along with other keys to perform certain functions. On Windows this can include alt, control, Windows key and shift along with other keys but space with the tab key at the same time isn't a valid keystroke. If that combination seems to do anything it's because your computer is processing and acting on one or more of those keys but you typically would choose either the space key or the tab key to perform a function. In most email interfaces pressing the tab key will likely move your focus from the to: field to the cc:, subject and then the message body fields although what field you move to will depend on the email program being used. Shift+tab moves in reverse.
