How can I archive automatically on reply in mail?
Apple's Mail.app doesnt have a feature to toggle for this, but you /can/ do this in Sparrow.
Sparrow has a lite version that might suit your needs, but the full version does what you ask.
The option I use to to have Keyboard Maestro intercept the standard send button key command, and then run a macro that
- Sends the message.
- Moves the message to my archive folder.
I set the macro for the standard Shift-Control-D. Keyboard Maestro intercepts that key command. It then executes the rule "Select 'Send' in the menu 'Message' in Mail", and then "Select 'Archive' in the menu 'Message' in Mail". Archive is the name of my folder. So Keyboard Maestro is just executing those commands in the menu, since there isn't any build-in keystroke for moving messages to folders in Mail.
