Is it possible to send mail using Command + Enter in Mail?

Question

I can't think of any reason why Command ⌘ + Enter ↩ would not send a mail draft, instead of the current shortcut, which is Command ⌘ + Shift ⇧ + D Is there a way to change this?

Answer 1

You can look at this answer and apply accordingly to your case.

TL;DR version:

Answer 2

I tried to use the System Preferences, Keyboard Shortcuts tab to define Command+Return to send a mail. But the effect was that Command+Shift+Return sends mail.
