Textual can only ever support key combinations that are passed on by your terminal application. Which keys get passed on can differ from terminal to terminal, and from operating system to operating system.

When creating bindings for your application we recommend picking keys and key combinations that are supported on as many platforms as possible.

The easiest way to test different environments to see which keys can be detected is to use textual keys.
