If any one wants to create a mechanical keyboard and use the controller board of the logitech k120 , there are some extra keys on the keymap that are not present on the actual keyboard but was present in the matrix , like the shortcut keys and the volume up and down keys , as well as the power and sleep keys.
the controller is under the blob
Ah, of course. That blob doesn't come off easily by any chance, does it?
nop it will destroy the controller i am pretty sure
