An information processing terminal acquires a plurality of object IDs identifying respective ones of a plurality of display objects. Each of the plurality of display objects is previously with a corresponding standard operation. The terminal acquires a plurality of operation IDs identifying respective ones of the plurality of operations, and displays a first screen to prompt a user to select an operation ID to be correlated to one of the plurality of object IDs. The terminal receives a first input to select an operation ID to be correlated to an object ID via the user interface after the first screen is displayed on the terminal display. The terminal generates instruction data and custom operation data defining a custom operation concerning an operation identified by the selected operation ID. The instruction data is information used for execution of the custom operation defined.
