If you’re on the Mailplane app there’s a “Save to Omnifocus” function under
the “Edit” menu that has the functionality I described, so I just gave it a
hotkey in my keyboard shortcuts in system preferences.
I have since overriden it with keyboard maestro though, and I programmed
keyboard maestro to call that function and then re-arrange the title of the
Omnifocus item to look like this:
“ | Subject line” (with the cursor at the beginning of it)
This way, I can clarify the physical visible action in front without any
additional keystrokes—
for example, “Call Dr. Lee to reference Ari | Re: Re: Onsite Interview
Follow-up”
I also programmed Keyboard Maestro to then pause until I save the omnifocus
task and automatically archive my email with the letter ‘e’ once it’s
there. The way my Gmail settings are set, Mailplane then takes me straight
to my next email.
I have another keyboard shortcut with keyboard maestro that I call “Send
and Waiting” that all at once sends the composed email, archives it, and
puts it into my @Waiting context in Omnifocus
