A first input is received in an animation creation application having a user interface showing a virtual-space area for first objects, and a timeline area for second objects representing events. To generate the first input, a user presses and holds an input control while a cursor is over one of the first or second objects. It is determined whether the input control is held for at least a predefined duration. If so, a copy of the object is assigned to the cursor, and the copy is…
