I'd like to know the syntax of creating a Custom Agenda Command in emacs org mode.
I found this tutorial on the org mode website. It says that the third argument to a list item in
Type of search
The desired agenda display/search. The options include agenda, todo, search, tags, alltodo, tags-todo, todo-tree, tags-tree, occur-tree, or a user-defined function.
There's some bits of information about these options sprinkled throughout the tutorial, but nothing definitive.
I checked the Custom Agenda Views section of the org documentation, and its children, but didn't even find the options listed.
I haven't read every page in the org documentation, but I've looked through any I thought would be relevant to my question. I also searched on google generally, and with
site:orgmode.org, but I haven't found any sources that outline exactly what how
tags-todo etc work.
Is this written somewhere?
