Do you need to self compile? The Linux port (https://github.com/elfmz/far2l) ironically only provides macOS releases... Thank you!
On ArchLinux there's package in AUR: https://aur.archlinux.org/packages/far2l-git (I maintain it).
Don't know details for other distros.
Ctrl + enter puts currently selected file/folder name into command-line.
Ctrl + O hides panels and shows you "background" with all the previous command outputs.
Custom editor can be set in F9 -> Options -> Editor settings.
Ctrl + PgUp - move up the folder tree
Ctrl + U - swap panels (so the cursor goes from one panel to another, useful when you operate in 2 folders primarily, saves you an Alt+Tab)
Ctrl + LeftArrow, Ctrl + RightArrow - makes one of the panels larger or smaller
Ctrl + 1,2,3,5 - change panel layout (file name 1 column, file name 2 columns, file name with attributes, file name with more attributes)
etc. There's a lot. Not even mentioning all the plugins built in the last 20 years.
Fun fact: it was written by a 24 yo college student (graduate?..) from Chelyabinsk and was pretty much functionally complete couple years later. The same guy who designed RAR file format and built WinRar around the same time.
mc has a "list of bookmarked directories", does far supports such a feature, with a shortcut to bring up the dialog to choose an entry from the list? I haven't found such thing... Only to have particular single directory on a shortcut, which means that I would have to remember the number corresponding to each path...
