Yeah, mutt also has a compose "mode/window." It's the window right
before you hit 'y' to send with all the data.

That's precisely the part I'm interested in. Turns out I have overridden
'f' with something else in my config and could not get to that
functionality. So then I launched mutt with -F /dev/null on the command
line to figure out which the name of the command that overrides Fcc.
It's simply "edit-fcc".
