Recently opened objects
Use the Recent Objects button available on the DB Explorer toolbar to access the list of recently opened database objects (during the current session).
This list is common for all registered databases. Next to the object name the database name and the host/address are displayed. Select an object from this list to open it using its editor.
To change the number of objects that are considered 'recent', select the Options | Environment Options main menu item, proceed to the Tools | DB Explorer section within the Environment Options dialog, and set the Recent objects count option value (see Environment Options for details).
