[Feature Request]: allow changing keyboard shortcut for 'full-screen' extension

[mawkler]

The extension full-screen is activated by pressing F. However, this clashes with the default key binding F defined in keyboardShortcut.js.

A solution to this would be to use a different key binding for 'full-screen', for instance Shift + F.

I preferred the old shortcut, which was alt+f (if I'm not mistaken). Perhaps a new feature where you're able to pick a shortcut, or a dropdown menu from pre-defined shortcuts?

Actually, it has always been the f key, but I'll still keep it as default and add the ability to change it via settings in the future.
