It's an interesting file browser, the default "blue" colors gives old-school vibes nowadays.

If you wonder how to quit (if started from a terminal):

It's `ESC 0`. Or "exit" like from a shell. Took me some time I have to admit (q, ctrl-c, ctrl-q, F10, ESC all did not work).

F10 always worked for me, but some terminals use F10 for some other functionality.

If that fails, you can click on "10 Quit" with the mouse (not ideal, but an immediate solution).
