You can open the Show Symbols dialog box in two different ways:
♦Select Symbol→Show symbols.
♦Right-click the diagram background and select Diagram→Show Symbols from the diagram contextual menu.
6HOHFWLQJ REMHFW V\PEROV
The Show Symbols dialog box displays all objects belonging to the current package. Object symbols are organized in different tabs, each corresponding to an object type. Only relevant tabs are displayed. For example, if you convert to package a diagram that only contains tables and references, only the Table tab will be available, as references are contained in table definitions. Shortcut symbols, extended dependencies symbols and free symbols appear in their own tab if any.

You can locate any object with associated symbol in a diagram or among several diagrams within a model using the Find in Diagram feature. Objects without graphical symbol such as domains cannot be found in the diagram.
When the object has only one symbol within the model, the corresponding diagram window appears with the object symbol selected in its center.
On the other hand, when an object has several symbols within a model, a symbol selection dialog box appears that lets you select an object symbol among all instances of the object within the model diagrams. When you click OK the symbol is selected and centered in the current diagram window.
