Panning and zooming at the current level

When the current level of the diagram is so large that it doesn’t all fit in the viewable part of the window, you can:

•      Hold down the CTRL key and roll the mouse wheel. Rolling the wheel forward zooms in on the diagram; rolling it backward zooms out.

•      Click on the  toolbar buttons to enlarge or shrink diagram components.

•      Use the scroll bars to pan to the parts of the diagram you want to view. If you right-click over a scroll bar, a Windows navigation pop-up menu appears. Select the navigation option that corresponds with what you want to do.

Typically, larger, more complex diagrams should be divided into subsystems and encapsulated in compound blocks.
