We have engineered AppGameKit specifically to gently steer you away from adding commands that do not convert well to other hardware or platforms. All tablets don't have right mouse buttons, and phones for that matter. Even some variants of Mac desktops have no right mouse button
We do allow you to read the right mouse button, but through the appropriately named RAW commands, which are clear indicators that you are accessing RAW data from the platform and your app will NOT perform universally across all platforms.
