Scratch Screen Navigation and Commands

The video tutorial explains how to navigate the Scratch interface using x and y coordinates. It covers the range of movement along both axes, with x ranging from -240 to 240 and y from -180 to 180. The tutorial demonstrates how to use the 'Go To X Y' command to move sprites to specific locations on the screen. It also highlights the importance of linking actions to events, such as clicking the green flag, to execute commands.
