To navigate to a particular resource in a view such as the Project Explorer view:
The view displays the selected resource.
If you want to open a particular resource in an editor rather than select it in a view, you can use the Navigate > Open Resource action. This action presents the same dialog as the Go To > Resource action, but immediately opens the matching resource for editing.
You can also do a contextual search for character strings contained within files in the Workbench. See the links to related tasks below.
