 - The `protocol_call` option is the name of the function in your AutoHotkey that will run in these cases. It defaults to `app_call()` if none is specified.

 Note: For example, if `protocol` is set to `myapp` and a `myapp://test/1234` link is clicked, the set `protocol_call` function will be called and will receive `test/1234` as its first argument. If `protocol` is set to `*`, the set `protocol_call` function will run for **ANY** link clicked and it will receive `myapp://test/1234` (the whole URL) as its first argument. This is not recommended for most cases, as links with `href="#"` will also trigger the function (usually unwanted behaviour).
