Selecting a stage

There are three ways to select a stage of the schematic. 

Select one of the components in the stage by clicking it, and then select menu Edit | Select Stage.

Right-click any one of the components in the stage and select Select Stage from the pop-up menu.

Drag the cursor over all five components of the stage.  Drag the cursor by clicking and holding the left mouse button while moving the mouse.  The selection area is shown as a dotted rectangle.  The stage is selected when the mouse button is released.  All five components must be within the selection area for the stage to be selected.  If more than one stage is within the selection area only the left-most stage in the selection area will be selected.  Only one stage may be selected at a time.  The selected stage is shown within a blue dotted rectangle and all components of the stage are individually surrounded by a blue dotted rectangle, as shown in the figure above.
