Creating a keyboard shortcut to set the current account in Apple Mail
If you have more than one email account setup in Apple Mail.app, it's nice to be able to select the one you want to send a message from without having to use the mouse.
Here's how to do it:
The "Menu Title" field must be exactly as your account name appears in mail when you are selecting the account you want to send a message from:
"Your Name <name@place.com>"
I like Control-1 for my first account, increasing in number for each account.
