Interesting. OTOH, people have named a number of similar tools, and I'm going to point out 'mc' aka Midnight Commander, which is part of most linux distro's, and is a clone of the 1980's Norton commander. Its designed to be a command line TUI helper, sorta like the project here, with not only cursor/etc based directory navigation but copy/rename/delete/etc functionality just a keystroke away. Its fairly convenient because it overlays the command line rather than replacing it.
