Abstract: Source and target objects are differentiated by an attribute visible to the user and detectable by an application with source objects and target objects residing in respective containers. When a user desires to perform multiple source and target transfer operations, the desired collection of target objects is first selected by interaction with the target object container, including range selection or pointer device clicks, whereupon each selected target object indicates selection. Using similar operations, one or more source objects is selected, the user interface thereafter displaying a collection of selected target objects and one or more source objects shown with selection emphasis. The source objects are then moved using a standard transfer function from the source container to one of the target containers. In the target container, all valid selected target objects in view then provide acceptance feedback by a visual indication that each of these user-selected objects will accept the drop action.
