The Worksheet

1. If the Worksheet is larger than the Viewport, scrollbars appear to assist navigation.
2. When you click the mouse on elements in this area (including vertical line segments), the corresponding text (if any) will be highlighted in the text currently showing in the lower tabbed pane.
3. When a function block diagram is displayed in this area, double clicking on the body of a function block instance will open its type definition in a new tab.
4. You can drag various elements in this area (including function blocks, connecting line segments, and elements of ECCs) to improve readability.
   • The "handle" for dragging a function block, resource or device instance is the element name at the top of the element.
5. You can select and drag multiple elements using Shift+Click and Shift+Drag gestures.
6. You can move selected elements around one pixel at a time with the Rosette.
7. You can add connections to a diagram using the Connect gesture.
8. The popup menu for this area contains the following items:
   • New - Presents options for adding appropriate elements to the diagram.
   • Worksheet
     • Larger - Increases the worksheet height and width by a factor of 1.5 without redrawing the diagram.
     • Fit to Viewport - Matches the worksheet size to the viewport without redrawing the diagram. This may cause the diagram to "overflow" the worksheet boundaries.
   • Scale - Allows you make the diagram larger or smaller in incremental steps.
   • Parameters - When this item is checked, all parameters are shown on the diagram; when it is not checked, parameter hiding is enabled.
9. Additional popup menus provide for editing the elements of ECCs, FB diagrams, Ladder Diagrams, interfaces, service sequences and system configuration diagrams.
