Keyboard, notification, or menubar shortcut to compose mail message? Im looking for a quick way to bring up a compose mail message dialogue.

Either a keyboard shortcut, or even a little tool within mountain lion's new notification center would be cool.

Anyone got anything?
The easiest way out-of-the box is to use the "services menu". Just select some text anywhere (a single character will do), right click to open the context menu and select the bottom-most item "Email Selection":



If it is not present (should be) you need to enable it under System settings -> Keyboard -> Keyboard commands -> Services -> Text
