Online Documentation for SQL Manager for Oracle
Using Script Explorer
The Explorer group on the Navigation bar displays the tree of objects, used in the current script and allows you to get to the required script fragment quickly by clicking the object in the tree.
Hint: When you click a node in the Script Explorer tree, the corresponding SQL statement is highlighted in the editor area. If you double-click a node, the corresponding SQL statement is highlighted, and the current focus is switched to the editor area (the cursor appears after the highlighted statement).
You can disable the Object Explorer to speed up the processing of big files with Hide explorer item or at Environment options|Object editors.
