# Opening an editor on a type

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

1. Press Ctrl+Shift+T or, select Navigate > Open 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. Hint: you can press the Down key to move to the first type.
4. Click OK when you are done. An editor opens on the selected type.

Note: The Open Type dialog maintains a history of recently opened types. These are shown when the dialog is opened and stay above a separator line when you start to type a filter expression.

Note: If you open a type from a CLASS or JAR file, you will see a special editor showing only method signatures unless you have attached source to it.
