External inter-application input field constraints that specify a configured association relationship between an input field utilized during execution by a first application and multiple input fields utilized during execution by a second application are generated in advance. In response to user input entered into the input field of the executing first application and based on the external inter-application input field constraints, context-aware input data to the multiple input fields of the concurrently-executing second application is provided during concurrent execution of the first application and the second application.
