Editing meta shortcut on nano text editor

Question

Is there any option to change the meta M- shortcut on nano text editor?

Im working with a Mac, and I wanted to change the meta shortcut for comfort reasons. I'm actually using the esc key but will love to change it to my preference.

You can rebind individual keybindings by editing your ~/.nanorc file to include keybindings. Unfortunately, nano only supports ^, M- and F as modifiers, so it would be difficult (not to mention tedious) to fit all M- keys elsewhere.
Instead, it might be simpler to rebind the key in your terminal program, or use an external hotkey remapping program. I have no expertise with the latter on Mac, but you could start looking here.
