23 0. Connect PS/2 keyboard into Teensy with 4 lines(Vcc, GND, Data, Clock).
24 By default Clock is on PF0 and Data on PF1.
25 You can change this pin configuration by editing config_pjrc.h.
26 In this photo Vcc is yellow, GND is green, Data is red and Clock is black.

40 Demonstration of Features
41 -------------------------
42 In default configuration, you can try several keymaps, mousekeys and USB NKRO.
43 Use following magic key combinations to enable some features.
46 Magic+0: Qwerty with mousekeys(default)
47 Magic+1: Qwerty without mousekeys
51 Magic+N: toggles NKRO/6KRO(6KRO by default)
52 Magic+Esc: sends Power Event(Power button)
54 where Magic=(LShift+RShift) or (LControl+RShift)
57 Fn0+(hjkl): Mousekey move(vi cursor like)
58 Fn0+(yuio): Mouse wheel(left,down,up,right)
59 Fn0+space: Mouse left button
60 Fn0+(mnb): Mouse buttons(m=left, n=right, b=middle)
61 Fn0+(zxc): Media control(Volup, Voldown, Mute)
62 Fn1+(hjkl): Cursor move(vi cursor like)
63 Fn1+(nm,.): Cursor move(Home,PageDown,PageUp,End)
70 You can change a keymap by editing code of keymap.c like following.
71 How to define the keymap is probably obvious. You can find key symbols in usb_keycodes.h.
72 To define keymap layer switching may needs a bit of your effort at this time.
