Create a New Email with Attachments Quickly by Keyboard Shortcut in Mac OS X

Dragging files into the Mail Dock icon is a quick way to send out email attachments, but if you’re faster with the keyboard, try setting up a keyboard shortcut to perform the same task instead. This makes any selected file(s) from the Finder just a speedy keystroke away from being sent off in an email:

• Open System Preferences from the  Apple menu and select “Keyboard”, then click on the “Keyboard Shortcuts” tab
• Choose “Services” from the sidebar, find “Messaging” and then check the box next to “New Email with Attachment”
• Click in the area to the right of “New Email with Attachment” and then set your keyboard shortcut, the example used Control+Alt+Command+A
• Close out of System Preferences and go to the Finder, select a file (or a few) and hit your keyboard shortcut to instantly create a new email with those files as attachments

For some OS X 10.8+ users, the “Services” submenu may not show the option under Messaging, and it may be under Application Shortcuts instead.

This great little trick comes to us from a comment left by Markus, give it a try!
