This screenshot shows the full Designer, and is intended to orient users to the five main areas of the screen: 1) the header, which runs the length of the screen along the very top; 2) the Navigator, which is a panel that lies at the far left of the screen, and which also contains a narrow ribbon at the extreme left with icons to open various editors; 3) the canvas, which lies in the middle of the screen, between the Navigator on the left and the Properties pane on the right; 4) the Properties pane, which is about the same width as the Navigator and lies to the far right of the screen; and 5) the footer, which contains four icons for accessing the debugging tools described in the text.
