The invention discloses a frequency converter keyboard, a frequency converter and a frequency converter identification method. The frequency converter identification method used for the frequency converter keyboard comprises that keyboard handshake data including keyboard type data is sent to the frequency converter; whether frequency converter handshake data including frequency converter model data is received from the frequency converter in preset time is determined; if the frequency converter handshake data is received, a model of the frequency converter is identified according to the frequency converter handshake data, and a corresponding function parameter configuration table is called to match the frequency converter; and if the frequency converter handshake data is not received, itis determined that the frequency converter keyboard does not support the frequency converter, and a corresponding prompt signal is emitted. Thus, the frequency converter is identified automatically, user parameters are set in corresponding to function codes, confusion of a debugging parameter is avoided, and parameters of the frequency converter are set normally when the parameters of the target frequency converter are debugged. When the model of the frequency converter cannot be identified, prompt is provided, a user can replace the frequency converter keyboard, and the time cost of debuggingcan be reduced.

Describes the control over interaction with the application launcher. Interaction with the application or multiple representations of content in the application launcher is controlled by the computing device. The plurality of representations are selectable for navigating to a user interface corresponding to a corresponding application or content. Controlling includes detecting which types of interactions with respect to the application launcher are used by the user. In response to detecting that a gesture-type interaction is used, a management mode is entered that initiates customization or commands of the representation using gestures outside of which the customization or commands cannot be initiated. In response to detecting that a cursor or keyboard type of interaction is used, the customization of the representation or the command is enabled using a cursor control device or keyboard, respectively, without entering the management mode.
