[FEAT]: list of key codes

[rwijtvliet]

Is your feature request related to a problem? Please describe. It's unclear how to refer to non-alphanumeric keys.

Describe the solution you'd like In the readme.md, add a few examples, e.g. how to refer to the windows key (win? meta? super?) and the control key (control? ctrl?), how to refer to the bracket keys, the semicolon, etc. Or just a link to a website that lists them.
