"That" (output) makes sense to me.

It's possible mc won't work fully with fish - it's designed to work with
bash, tcsh, and zsh (that is 'if' you mean the shell fish, rather than
the "file sh"/fish network protocol)

Because you don't always 'need' to see the output of a command - unless
it was unsuccessful. e.g.:-
rm test*
touch test
mount /dev/sdg2 /mnt

As previously suggested - you have some keys pre-assigned.

NOTE: there are two "super keys" SUPER_L (left, keysym 0xffeb, keycode
133) and SUPER_R (right, keysym 0xffec, keycode 134).

Before you try assigning mc hotkeys to use other meta keys see my
comments further down about mc and Esc as a meta-key. Note that any key
can be set as a meta (*modifier*) key - but assigning them for terminal
use is a little tricky as you'd probably have to modify the terminal
handling of the keys as well as the app (e.g. mc).

You'd be best getting help with Unity/Ubuntu/GNOME from someone who
actually use it (not me).

I'd suggest you stick to default settings until your experience is
complete enough to safely start tweaking/hacking your setup *especially*
if you don't keep detailed notes of changes.

The reason I suggested mc in the first place was that it's useful for
newbies when working in a *non-gui* (text mode) environment. i.e. a
terminal session on your phone, using it on your Ubuntu whatever desktop
is kind of redundant as your file manager has the same capabilities.

mc hot key designations are in /etc/mc/mc.keymap and ~/.mc/mc.keymap
man mc
/Redefine hotkey bindings

You 'can' change the mc hotkeys to ones that are *not* used by Unity -
but if you do I'd suggest you cp /etc/mc/mc.keymap ~/.mc/mc.keymap and
then customise the local config file. But first ensure you have a
*compelling* reason to change things in the first place as it could
result in you becoming more confused(?)

"Midnight Commander allows the Esc key to function as a Meta-key. In
cases where a function key or Alt-key combination is not available due
to interference from outside programs, use the Esc key instead. For
example, to input the F1 key, press and release the Esc key followed by
the "1" key (use "0" for F10). The same method works with troublesome
Alt-key combinations. For example, to enter Alt-t, press and release the
Esc key followed by the "t" key. To close dialog boxes in Midnight
Commander, press the Esc key twice."

mc -> Options... -> Learn keys...

and read the fine mc man file just in case you are asking questions you
could answer yourself e.g. don't skip the section on Miscellaneous Keys
man mc
/Miscellaneous Keys

NOTE: most of the info from the man file can be found in mc's internal
help (press F1). Pressing F1 is also good place to start looking for
help in most gui programs.

It's possible mc doesn't have an abbreviation for keys that are specific
to Microsoft keyboards.
