How do I use Mail.app search and replace without the mouse A recent update to Mail.app in Mac OS X changed the UI of the search and replace when composing a new message.  The old version could be driven 100% from the keyboard while the new one requires using the mouse to click the Replace check box as well as hitting the "all" and other buttons.

Is there a way to drive this interface without using the mouse?
If you enable full keyboard access from System Preferences > Keyboard > Keyboard Shortcuts, you can focus the buttons by pressing tab and select the focused button by pressing space.
