There's one powerful thing that mc does and almost any other dual file manager omits: it has the concept of "pop up menus" for commonly used commands --with the option of sending the selected file(s). Also, these menus can be global or local, configured for each specific folder or in my case working copies of some proprietary version control repositories (Subversion was too cool then).
Not only viewing files with F3 instead of using 'more' made you go significantly faster when there was no IDE to quickly grok a codebase, in ancient times where version control and diffing and merging was not exactly like today this was extremely powerful, only surpassed by Emacs.
Edit: to add that in macOS Forklift has something like this in a specific "Tools" section.
