The Element Navigator is shown in red in the figure below. You can perform the following operations in this panel:

• You can click on an element to Select it:
  • If the element has a graphical representation, that will be displayed in the Worksheet area.
  • If the element does not have a graphical representation, a default display for the library element (typically its external interface) will be displayed in the Worksheet.
  • If the element has a textual representation in any of the tabs of the Text Panel, the corresponding text will be visible under the tab.
  • If the element does not have a textual representation in a particular tab of the text panel, the text under that tab will be scrolled to a default location (typically the top of the text).
• Where feasible, you can Edit an element in the Element Navigator tree by double-clicking on its tree node.
  • In general, an element on the tree cannot be edited if it can be edited in the Worksheet.
• Where feasible, you can perform other operations using the popup menu on a tree node. Examples of this include:
  • adding an Application to a System via the popup menu on the Applications node;
  • adding an Algorithm to a Basic FB Type via the popup menu on the Algorithms node;
  • Running a System or an FB Type via the Run option of the root node's popup menu.
• When feasible, you can use Drag and Drop to change the order of elements in a list.
  • Dropping an element on another element in the list will result in the dropped element assuming the position of the target element.
  • For instance, in the example below, dragging the LOG resource onto the CLAMP resource in the DIAGNOSTICS will result in the order of resources in the device being changed to {CLAMP,LOG,MONITOR}; this will affect the order in which these resources are created and initialized when the DRILL_MVCDL System is run.
