The back button is unpredictable and may take you out of your current tool or site. Instead of using the back button, use the internal navigation features of Trunk. Most screens have a “Cancel,” “Clear,” or “Back” button at the bottom of the page, which should allow you to navigate back one page.
You can also use the Reset and Home buttons. The Reset button will take you to the homepage of the tool you are using and the Home button will take you to the homepage of the site.
