The actions menu for a database object in the Databases tab consists of actions that are available for the selected object type. Some of the operations are common for any currently selected object while others are only available for the current object. Sometimes it is convenient to run a single action on multiple nodes at once. To do this, select the nodes (make sure all are of the same object type) and then right-click in the object list. The menu will now highlight those actions that are valid to use.
Choosing for example the Drop Table action shows the following window in which the drop can then be performed on multiple tables.
