You write, "You then have to type the command plus file name, and the only thing that helps is tab completion." I can see your point because for many years I used cd, ls, mv, etc, to do all my file management and all of my browsing around my local file system. When I switched to software (Emacs's Dired subsystem) that let me specify the file to be acted upon without my needing to type the name of the file, it was a distinct improvement. (I usually use the page-up and page-down keys to find the page containing the file name I want, then use the mouse to specify the file.) Thanks for your reply.
