Hi,

I think the original problem is fixed. Now it is a question of how the fido should behave. 

The only thing I would suggest for Emacs 27 is to update the documentation of fido? This is what confused me because M-j is not mentioned by 'M-x describe-mode' and C-M-i is not the correct key for the situation where there are no matches. This confused me.

Thanks!

----

When this global minor mode is enabled, typing in the minibuffer
continuously displays a list of possible completions that match
the string you have typed.  See ‘icomplete-completions’ for a
description of how prospective completions are displayed.

For more information, see Info node ‘(emacs)Icomplete’.
For options you can set, ‘M-x customize-group icomplete’.

You can use the following key bindings to navigate and select
completions:

key             binding
---             -------

C-j		icomplete-force-complete-and-exit
ESC		Prefix Command
C-,		icomplete-backward-completions
C-.		icomplete-forward-completions

C-M-i		icomplete-force-complete



Line-Number minor mode (no indicator):
Toggle line number display in the mode line (Line Number mode).
