You're welcome, but I think Juri did most of the work.

I had planned to tackle this some time ago but it got lost in
somewhere in the bucket of TODOs.  I haven't given it much
testing,  but I'm suprised it works the way it does.

I imagined it would show the typical constantly-adjusting
fido-mode/icomplete list of candidates in the echo area, but it
doesn't, only for in-buffer instead of minibuffer.
Instead, it seems to popup *Completions* as usual.

Am I being dense here? How do you set it up? Is it just
(setq icomplete-in-buffer t) + M-x fido-mode as I did?
And how do you invoke it? Is it C-M-i?

This probably makes sense, but please, for my benefit, try to show
a minimal config with just Emacs -Q and your keybindings that
you want to use in both fido modes.
