For the Tankstick: 2 of the buttons are native for mouse and many pinball games such as Visual Pinball that do not have native mouse button support for gameplay. Thanks to a program known as AutoHotkey you can! By creating a custom config file for use with these pinball emulators, we created an easy to use program that you simply start before playing them.

Download the X-Hotkeys program. Simply run it before playing a pinball game and it changes the mouse buttons to the default keyboard keys used for needed actions as listed below. Default action is Nudge Left and Right. Keep in mind it only works when one of these Pinball games is running. 

~ (Tilde) = Toggles X-Hotkeys on and off, tray icon will show 'X' (or H) when active, 'S' when suspended.
