+- Key map
+
+In normal terminals, if you press 'D' key, it will be echoed as 'd' on screen.
+And press 'Shift + D' prints 'D' on screen. Shift key works to flip caps. 
+
+However, napple1, if you press 'D' key, it will be echoed 'D'. All letters 
+you can type is upper case only. Because original apple1 has a limit to do so.
+And shift key works like a control key in napple1.
