From the command line, use "start [link]" in Windows, "open [link]" in OSX, and "xdg-open [link]" in SteamOS/Linux. Note that a controller must be active to apply a configuration. Links will be shown in the controller type they were created for, but will be converted to the controller type they are being applied to on application
