Your question is a bit confusing: ^S saves the file, but you want to run
the formatter /after/ that but before saving the file???

Anyway, how about creating a little script that first runs /bin/nano on
all arguments, and then checks each argument in turn and runs whatever
on it when it is a Go file?  Then alias nano to this script and presto.

If instead you want ^S to format the buffer before saving it to disk,
then you need to rebind things.  Say 'bind M-5 savefile main',  and
'bind ^S "^[f^[5" main' (where ^[ is a literal escape), which causes
^S to act as if you pressed M-f followed by M-5.

Yes, this is exactly what I wanted and it works like a charm. Thank you.
