Running spacemacs 0.200.13 on emacs 25.2.2 on Kubuntu 18.04.
Just as the title suggests, I want to search for all agenda items without an active timestamp --- either plain active timestamp or a scheduled or deadline timestamp.
How do I do that?
A solution is given here for selecting tasks without a scheduled or deadline timestamp. But that does not work for me. Emacs just goes in some kind of a loop. Agenda is not generated even after 45 secs. Moreover, it does not cover tasks with just a plain active timestamp.
