(mutt is an email client…)
this tip on filtering/ limiting was exactly what i needed right now. it’s
been a while since i went over from mutt to gmail, but i still handle some email with mutt.
When I come across a message that I’d like to read more closely, or that needs a reply, I flag that message as “Important” by pressing the “F” key. Then
at a later time I can ask Mutt to show me only the flagged messages with a command like “l ~F“.
