A device with controllable mechanical characteristics makes available a list of controllable characteristics for use by a controller or host computer. The list may include not only controllable characteristics but also the available range for each control, the impact of each adjustment, or both. The host computer can evaluate an operating state of the computer or electronic device and determine how best to set the device for compatible operation with the operating state. When controllable characteristics have multiple effects and/or interact with other controllable characteristics, macros may be developed to perform multiple settings as a group to achieve the desired outcome. The list may also be downloaded from a web service.
