It does not do that, I just double checked, even when the focus is on the "Send" button a dialog box pops with "Send (Ctrl-Enter)" and no sending happens. Maybe what you encountered was the work of a browser extension or a labs feature left enabled, or most likely you just tapped return at the wrong moment.

It may not have done it for you, but it did it for me, and others in this thread have confirmed that it did it for them.

For reference, I don't have any browser extensions installed, and I haven't used any labs features, so neither of those suggestions is correct either.

And forgive me for being blunt, but your reply seems to be similar to what happens when a problem is reported to some "support" services where they say "Works for me!" The clear underlying text is "So you're an idiot, and don't matter."

So thank you for your suggestions, but they're wrong. And it did do it for me, and I double-checked.

I think maybe you should take a step back and realize that the way you communicated your message initially isn't consistent with the defense you're making here. You didn't state your original issue as a bug, you called Google out as if this were some kind of feature:

"People, when you design an interface, don't put invisible, undiscoverable, irrecoverable actions in it."

This would only be a feature if it happened for everyone, and now you're using curt language with someone who is trying to help.

Troubleshooting is hard, and the communications involved are often polarizing. End users commonly feel defensive, and troubleshooters often fail to couch their language diplomatically.

The matter of reproducibility is the basic litmus test by which programmers classify issues as bugs versus environment issues. Bugs are problems in the software, and environment issues are problems in the user's specific configuration. Often times an issue is a combination of both. The willingness to engage in troubleshooting environment issues varies by developer, but if you're interested in receiving help, it's worth acknowledging that your problem falls somewhere on this continuum, which means you always bear some responsibility in remaining objective during the troubleshooting process. You seem convinced that this is some type of feature issue, rather than remaining open to other possibilities.

I think I might have an idea about what's happening in your case, but I'm reluctant to even posit the idea, because I fear you'll lash out as me as well.

You are blamed just like you blame the interface designers. Don't be mad.

Fact is, most reported problems, in the end, are caused by the user him/herself, so his response is not that bad.

I was honestly just trying to help. I tested the only way I know how, via my own Gmail account.
