+@chapter Keyboard Codes
+
+Keyboard servers receive scancodes from keyboard
+drivers. A scancode can either be comprised of
+one byte or three bytes. In each byte, the most
+significant bit (assuming unsigned bytes) is
+ignore, however for it first byte in the scancode
+it signifies whether the key was released: it is
+set of the key is released, and not set if the key
+was pressed or is being held down.
+
+A scancode is comprised of three bytes if the lower
+7-bits of the first byte is are all cleared, and the
+highest bit in the two following bytes are set.
+
+Ignoring the most significant bit in all bytes, the
+keycode is the value of the byte if the scancode
+is a single byte scancode. If the scancode is comprised
+of three bytes, the first byte is ignored and the
+keycode is @math{a \cdot 128 + b} where @math{a} is the
+value of the second byte and @math{b} is the value
+of the third byte.
