Type Safety for keys

[dcodesdev]

It would be nice to have type safety for the keys instead of just accepting string | string[]

Accepting string literals instead of generic strings, for example:

type KeyboardKey = "a" | "b" | "c" | "d" | "e" // etc.

type Key = KeyboardKey | `shift+${KeyboardKey}` | `ctrl+${KeyboardKey}` // etc.

const myKey: Key = "ctrl+c" // OK

const invalidKey: Key = "some+random+key+a" // TypeScript error
