+            When the test starts, you will see a Frame with two components in it,
+            components look like colored rectangles, one of them is lightweight, one is heavyweight.
+            Do the following:
+            1. Click the mouse on the left component.
+               If it isn't yellow after the click (that means it doesn't have focus), the test fails.
+            2. Press and release ALT key.
+               In the output window, the text should appear stating that those key events were consumed.
+               If no output appears, the test fails.
+            3. Press space bar. If system menu drops down, the test fails.
+            4. Click the right rectangle.
+               It should become red after the click. If it doesn't, it means that it didn't get the focus, and the test fails.
