Wow. In over 28 years of using Apple computers, this is the first time 
I've seen a menu item change in response to the control key. To say this 
isn't particularly discoverable is to put it very mildly.

In my opinion the Edit as New Message command should be ⌃⇧⌘D so 
that Cancel Send toggles to Send Now by pressing the option key, just as 
Delete toggles to Delete Now by pressing the option key. The use of the 
option key to toggle to command variations is common.
