I think that's why I've never shifted from vi to nano, it appears to be a regular editor but ignores all common key bindings, ctrls+s doesn't save, ctrl+f doesn't find, ctrl+h doesn't replace, etc.

I just fired up Nano on Ubuntu 18 installation. When I typed Ctrl-S, I was prompted for a file name. Nano saved the buffer into that file. I then made edits and used Ctrl-S again; it saved again without prompting. Furthermore, if nano is invoked with a filename argument, then Ctrl-S doesn't prompt. Ctrl-H is indistinguishable from ASCII backspace; if it does anything other than erase the character to the left of the cursor (possibly after climbing to the previous line, if the cursor is at the start of a line), it is objectively, positively wrong. You can distinguish Ctrl-H from backspace in a GUI system where you get detailed keyboard events. Nano has to work in a terminal.

  You're right ctrl+s works, I tried it, I always thought it had to be ctrl+o since that's what the bottom panel shows. I was encouraged so I highlighted some text then tried ctlr+c and ctrl+v, unless I hit a wrong key somewhere, it didn't work.

    Ctrl-C and Ctrl-V are not common keybindings, unless we are talking about the Microsoft Windows environment, and graphical environments aped after it. In the GNU/Linux environment, the standard keybindings are the Emacs-derived ones. Ctrl-A to go to the start of the line, Ctrl-E to jump to the end, ... pasting is called "yank" and mapped to Ctrl-Y. Your point stands since GNU Nano doesn't stick to these either. Ctrl-C is interrupt in the TTY environment. This is so entrenched that programs which obtain Ctrl-C as ordinary input rather than a SIGINT signal still use it for interruption. E.g. in Vim, we can use Ctrl-C to interrupt long operations. Ctrl-V is entrenched as a "verbatim" key: insert the following character literally, even if it is a control character.
