+I came across an email on one of the emacs mailing lists today, where
+someone asked how to ask a user for input whilst providing
+completions.  The first answer he got was to try `tmm-prompt`, so I
+looked into it a little.
+
+I use `mu4e` as my primary email program, but since it isn't designed
+(seemingly) for use with multiple accounts I've got some wrapper
+functions that set some variables according to my liking and then
+start `mu4e`. This works very well, but it's a pain to have to use
+`M-x view-ryu-mail` or `M-x view-ninthfloor-mail` and such, so I wrote
+a function to read a string from the minibuffer, which I then bound to
+the `<XF86Mail>` key, this turned it into, for example `<XF86Mail>
+ryu` and `<XF86Mail> ninthfloor` and so on, but this doesn't have any
+completion or notification of my options.
+
+So after looking at `tmm-prompt` I came up with the following:
+
+[[!format el """
+(defvar oni:mailbox-map
+  '(("ryulash.org" . "ryu")
+    ("ninthfloor" . "ninthfloor"))
+  "A mailbox map for use with `tmm-prompt'.")
+
+(defun view-ryu-mail ()...)
+(defun view-ninthfloor-mail ()...)
+
+(defun view-mu ()
+  (interactive)
+  (let* ((tmm-completion-prompt "Choose a mailbox\n")
+         (inbox (tmm-prompt oni:mailbox-map)))
+    (funcall (intern (concat "view-" inbox "-mail")))))
+"""]]
+
+I've left out the definitions and some mail accounts for brevity.
+
+`tmm-prompt` is usually used when using the text-mode menu with
+
+``M-` ``, but it works very well here too. This changes mailbox
+selection to, for example `<XF86Mail r` or `<XF86Mail> n`.
