I work mostly with a keyboard. It’s a 30-plus-year habit. The mouse is a secondary tool. I started with Norton Commander back in the 80s, then I used Volcov Commander, then I switched to using CONNECT by Dmitry Orlov, and finally to FAR Manager by Eugeny Roshal on Windows machines.
I use FAR Manager today, too, and I am deeply thankful to the people who continue developing it. FAR Manager became the first tool I install on each new machine, and it is the tool I use the most on a daily basis.

It turns out that FAR has also been ported to Linux, and I’m ashamed that I discovered it only today. The project is called “far2l” and is located here: GitHub – elfmz/far2l: Linux port of FAR v2. It works fine in Ubuntu, and I read it even works on Mac! I know there is MC (MidnightCommander), but I do not like it, so finding the FAR port for Linux was a huge surprise.
Moreover, if you stumble upon a Linux variant in which far2l is not available, there is a good chance that you can still use it by downloading a “portable” pre-compiled binary variant of far2l from here: Releases · spvkgn/far2l-portable
