What is the keyboard shortcut to send mail in Google Inbox? I often use a bluetooth keyboard with my tablet and use keyboard shortcuts everywhere. 
In the Gmail app and in the web versions of both gmail and inbox, the shortcut to send a mail you're writing is ctrl + Enter. This shortcut doesn't work in the Inbox app for Android, but it seems there is a shortcut, because I've accidentally sent emails before finishing them, but I don't have a clue what triggered the action.
A Google search didn't give me an answer to this question, so I'm asking here. What is the shortcut to send a message went composing a message in the app version of Google Inbox?
According to Keyboard shortcuts for Gmail, Ctrl + Enter is the correct shortcut for sending emails on Android (just as the other version stated in your question).
