+When I was first looking into improving my mailbox selection function
+I was looking at how to just ask the user for input with
+completions. Though now that I came across `tmm-prompt` I really
+prefer this way of working, at least in this case.
+
+However, today another function was mentioned, in response to someone
+pointing out `org-completing-read`: `completing-read`. Wow that's a
+far leap.
+
+Anyway:
+
+[[!format el """
+(completing-read "Your favorite color: "
+                 '("red" "green" "blue" "yellow"))
+"""]]
+
+This will ask for user input and provide these options as completions,
+but it won't show a list of options, of provide shortcuts, like
+`tmm-prompt` does.
+
+It's good to know these things, and I really should read both the
+emacs manual and the emacs lisp reference manual at some point.
