I need Linux support

So it's mildly OS dependent. From what I could tell, on UNIX systems, <termios.h> library has a bunch of functions to interact with terminal settings.

There is apparently an option for "raw" input, causing the program to read each character as typed as opposed to waiting for the enter key and parsing the line as a whole. Then stuff like the arrow keys or a backspace would result in special character combinations.

I've not used this before, but that could be a start for your own research

As far as I know raw mode can't detect those keys alone, but I'll check.

I was inferring based on this
https://stackoverflow.com/questions/22572983/termios-h-how-to-use-special-characters
Where backspace was rendered as ^?.
Again, never used it before, so I could be misunderstanding something

Thanks! I’ll let you know if it’s what I needed.
