For sending a mail, I am bound to the key combination CMD+Enter (⌘↵ ). Of course the Mac OSX default mail application, Mail.app uses something else.
I won’t even spend time on finding out the combination for sending mail using 3 keys so I get tendonitis after 5 emails sent.
There is an easy way to create shortcuts for basically everything in Mac OSX. Let’s set up ⌘↵ for sending emails in Mail.app. To do this, let’s open up System Preferences and select the Keyboard section.
System Preferences / Keyboard
Go for the Shortcuts tab in the top menu.
App Shortcuts
Select App Shortcuts from the list on the left of the screen and then click the + button underneath the list of current shortcuts.
Select Mail.app in the Application dropdown menu
After selecting Mail.app in the Application dropdown menu, the Menu Title: Send
and the Keyboard Shortcut is: ⌘↵.
Click Add and enjoy sending mails like you did in Thunderbird, Gmail or any other mail application.
