To add a Rectangle to the graphics pane:
1. Select Rectangle from the Drawing Toolbar or the main menu under Graphics|Insert.
2. Place the cursor at the location in the graphics pane where you want one of the corners of the rectangle to be.
3. Left-click and drag the line to the location of the opposite corner of the rectangle.
You can move a rectangle by selecting it and dragging it around the graphics pane.
You can "stretch" a rectangle by selecting the object and dragging one of the "handles" (there are eight handles - one on each corner and one on each side). Pressing the Shft key while resizing the object keeps the same aspect ratio; pressing the Ctrl key while resizing keeps the center of the object at the same location.
You can rotate a rectangle by selecting the object and choosing Graphics|Rotate from the main menu.
