# Open Type

This command allows you to browse the workbench for a type to open in an editor or type hierarchy

- Select a type to open: In this field, type the first few characters of the type you want to open in an editor. You may use wildcards as needed ("?" for any character, "*" for any string, and "TZ" for types containing "T" and "Z" as upper-case letters in camel-case notation, `e.g. java.util.TimeZone`).
- Matching types: This list displays matches for the expression you type in the Select a type to open field.

The behavior of the Open Type dialog can be further customized using the dialog menu:

Open Type Preferences
Option | Description | Default
--- | --- | ---
Fully Qualify Duplicates | When selected, duplicate matches are displayed using fully qualified names, packages, and container information (e.g. the package and containing JRE) | Do not fully qualify
Show Container Info | When selected, the Open Type dialog shows an additional bar at the bottom of the dialog which displays the package and containing JRE of the selected type | Do not show container info

Additionally, the dialog menu allows to use working sets to further constrain the matching types.
