+Sit down in front of the Commander X16 keyboard and look at the keys.  If
+you're familiar with regular computer or typewriter keyboard, you'll notice
+that the X16 Keyboard's keys are different.  Rather than just having letters,
+numbers, and punctuation on them, you'll see that most keys also have one or
+more "graphic characters" printed on them.  While the regular characters can be
+typed by simply pressing the keys, the graphics characters can be typed by
+holding down either \shiftkey or \altkey and pressing one of the keys with
+graphics characters.  For example, try holding down the \shiftkey key and
+pressing the \keybackgroundcolor{white}\key{s} key.  Instead of an 'S', a heart
+should appear on the screen.  Now press and hold down the \altkey key and press
+\key{s}.  This time a right-angled graphic character should appear.  Holding
+the \shiftkey key causes the graphic character on the right to be typed, and
+holding the \altkey key causes the graphic character on the left to be typed.\\
+
+Graphic characters can be used to create larger shapes and images on the
+screen.  For example, the graphic characters that can be typed by holding
+\altkey and typeing \key{a}, \key{s}, \key{z}, and \key{x} can be used to
+create a square that is larger than a single character.  If you include the
+graphic characters that can be typed by holding \shiftkey and typing \key{c}
+and \key{b}, you can draw a rectangle as large as the entire screen!  If you
+want your rectangle to have rounded corners, you can use the graphic characters
+on the \key{u}, \key{i}, \key{j}, and \key{k}.\\
+
+Spend some time experimenting with the other graphic characters to see what
+kinds of shapes and designs you can draw.  You can use the arrow keys to
+position the cursor wherever you need to type.\\
+
+% To start, sit down in front of the Commander X16 Keyboard and type the
+% following:\\
+% 
+% Hold down the \shiftkey key and press the \clrhomekey key.  Then type
+% \keybackgroundcolor{white}\key{N}\key{E}\key{W} and press the \returnkey key.\\
+% 
+% This will clear any program currently programmed so that the X16 is ready to
+% accept a new one.
