Some common interactions are moving the mouse, clicking the mouse, clicking a button, typing in a text field, selecting an item from a menu, closing a window etc.Drag a Flowchart activity from the Toolbox and drop the flowchart within the Major Giving Service sequence activity below the Initialize Workflow sequence activity.
