Could it be posibble the authors first language is gendered, because this sounds like something I would say in Lithuanian like when I talk about computers I use he because the word has a male gender.

There are exceptions to everything.

nano is just a text editor, I use it as a text editor, it has keybindings on screen by default, no need to config or memorise, why bother? (for text editing, not whatever people use vim or emacs for)
