Still doing the same thing, but perhaps reducing keystrokes to 2 total.

In your ~/.vimrc file, map a key sequence of your choice to do the work.
For example:

   map <f3> !Gpr -t -d^M:wq^M  

Here I'm mapping my function key F3.  I sometimes use ",," or ",x" as
my mapped sequence.

Editing your message from the index positions the cursor on the first
blank line after the headers.  "!G" sends line to a filter.  The lines
are the current one to the end of the file.  If you want the headers
sent to the filter shift the cursor first.  Such as:

   map <f3> 1G!G.......

My example filter "pr -t -d" merely double spaces the lines.  Replace
with a call to your filter.

The ^M (essentially <Enter>) is typed in as <ctrl>-V followed by the
<Enter> key.

The modified message is then saved and the editor exited with:

   :wq^M

The ^M typed as described above.
