When Valve announced that it had sold over half a million Steam Controllers, it also noted a new feature on the way called Activators. With Activators, gamers can customize each press of an input on the gamepad, with tweaks for haptic settings, or distinguish between a normal press, a long press or a double tap -- all on a single input. Now the feature is live for users in the Steam beta, to try out and see if there's another level of precision for controller customization.
