I need to use hotkeys like `Ctrl` + `9` + `8`, or `Ctrl` + `A` + `B`.

Autohotkey documentation [here](https://www.autohotkey.com/docs/Hotkeys.htm) says that combinations of three or more keys are not supported. However `Alt` + `Ctrl` + `Shift` + `X` modifier key combinations are supported, where X can be an alphanumeric character.
