To select a component, simply click it with the mouse pointer. Handles (black squares) will appear around a selected component. You can also select multiple components; for more information, see Grouping Components.

 

If you have components overlaid, you may want to select a component that is not the uppermost component. To do so, press ALT and click the uppermost component to select the second component in the stack. Continue to press ALT and click to select each of the components in the stack, one at a time (use ALT + SHIFT on the UNIX operating system).
