+<sect1>Keyboard codes<p>
+
+For direct keyboard scanning in conjunction with e.g. the OS location "CH" (764/$2FC),
+all keyboard codes are available as defined values on C and assembler side.
+
+Example:
+<verb>
+...
+ while (!kbhit());
+ switch (PEEK(764))
+ {
+ case KEY_RETURN:
+ ...
+ case KEY_SPACE:
+ ...
+ case KEY_1:
+ ...
+ }
+...
+</verb>
+
+You can find the C defines in the file "<tt/_pokey.h/" or "<tt/atari_pokey.inc/" for the assembler variant.
