Mechanical keyboard on Mac OS. When the right command key does not work properly.

Recetly I decided to switch from an Apple magic keyboard to the on of the mechanical keyboard I bought the other day on the Aliexpress. It's the GK85 one with red switches. Despite the fact this keyboard wasn't expensive the typing felt pretty good. Although the keyboard was compatible with the Mac OS, I faced that the right command key did not work as expected. Then the Karabiner Elements app came to my aid. In Karabiner-EventViwer I was able to determine the correct key-code that was associated with this key. In my case it was {"key_code": "application"}. So, there was just one thing left to do - map this key_code to the key_code I needed - right_command:

Simple Modifications ->
  For your device (select it) ->
    Add item -> application (Keys in pc keybords) ->
      right_command (Modifier keys)

There you go - it started functioning well.
