+You can send Sun protocol commands with TMK `Magic` key combo. By default `Magic` key is `LShift` + `RShift`, `LAlt` + `RAlt' or `LMeta` + `RMeta`.
+https://github.com/tmk/tmk_keyboard#magic-commands
+Following Sun specific commands are available. For example, to send 'Bell On' you can press `LShift` + `RShift` + `Up` keys simultaneously.

+Lightpad keypad firmware
+======================
+Korean custom keypad designed by Duck.
+*Note that this is not the official firmware*
+Supported models
+----------------
+All pcb options are supported.
+Build
+-----
+Move to this directory then just run `make` like:
+    $ make -f Makefile.lufa
+Bootloader
+---------
+The PCB is hardwired to run the bootloader if the key at the `top left` position is held down when connecting the keyboard.
+It is still possible to use Boot Magic and Command to access the bootloader though.
