When the check mark is displayed beside Use TrailBlazer Browsers in the Tools menu, a TrailBlazer browser opens when you select an option for a browser that displays code. For example, selecting Browse Applications from the Tools menu opens a TrailBlazer browser on applications in your image.

You can change the lists of components displayed by clicking on the navigation bar in the middle of the window. Or you can select options from drop-down menus above the window's panes.
