Today's Smalltalk 4 You takes an overview look at the browser set in VA Smalltalk (omitting the ENVY specific ones - we'll go through those in a separate tutorial). If you prefer a written walkthrough to video, then skip down to it. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

Once you have the inspector, you can drill down on any element by double clicking on it. You can also open a little execution workspace attached to the inspector - go to the Options menu and select Workspace:

Finally, if you want to capture a screenshot (of the window or entire screen), you don't need to leave VA for that. Simply open the Options menu again, and follow the Snapshot pull right. There are various options for what you can snapshot, and how to save what you decide to grab:
