nano ~/.config/mc/mc.keymap

[filemanager:empty-cmdline]
ChangePanel = tab

[input]
Complete = tab

Change time display in midnight commander to numeric:

Open ~/.config/mc/ini
Change timeformat_recent and timeformat_old settings to the same format string (in my case, to %F %T, which is YYYY-MM-DD HH:MM:SS)
Save ~/.config/mc/ini
