# Opening an editor on a type

You can open an editor on any type in the workbench.

1. Press Alt+Shift+A or, select Navigate > Open AspectJ Type from the menu bar. The Open Type dialog opens.
2. In the Choose a type field, begin typing an expression to narrow the list of available types, using wildcards as needed. As you type, the list is filtered to display only types that match the current expression.
3. In the Matching types list, select a type. When there is more than one definition of a type, then select a package in the Qualifier list.
4. Click OK when you are done. An editor opens on the selected type.

Note: The Java development tools Open Type dialog (Ctrl+Shift+T) can also be used to open Java types. See the Java development user guide for more information.
