When working with parts in VisualAge, you will use the following fundamental techniques: dragging objects, selecting multiple items, and displaying pop-up menus.
To drag a part, click and hold down the appropriate mouse button (see note below). Move the mouse pointer to the point where you want to position the part you are dragging; then release the button.
To select multiple parts, hold down the Ctrl key and click mouse button 1 on the items you want to select. This is referred to as a selection set.
To display pop-up menus, click the appropriate mouse button on the part in the Composition Editor or Parts List.
