This is a demonstration of my old modified keyboard's features.
Firstly I'm showing Menu and sequences list (View). Then adding a new one at position 2, that will type: "Hello World!".
I already have others saved, e.g. typing make,enter.
Also note few macros at positions 3 to 5.
The 5th does press Ctrl-Z (undo).
At 0:59 I'm showing page 3/3 with other sequences.
After that I'm pressing Backspace which reloads previously saved settings from EEPROM (was 124 Bytes).
Left blue LED is for layer 2 (sequences use).
Right orange is for layer 3 (mouse move, player, F13-F24 extra keys etc. I forgot to show these).
The program on left shows keys press/hold. Note that when I use macros or sequences they show up very quickly.
At 1:35 you can see Help. At 1:52 is the keyboard Status page. It shows protocol (Boot or NKRO), current Layers stack and mouse move variables.
Later since 2:04 I'm showing mouse moving and acceleration using keys. Also mouse buttons pressing using keys.
Lastly at 3:05 shortly showing Plasma (couldn't resist).

Using Kiibohd controller, it had the benefits that come with the software already.
