The designer is a newly graduated college student. When he was at school, he came up with the idea of designing such a keyboard. His idea was recognized by teachers and schools, so with the help of schools, he applied for a utility model patent for this keyboard.
He designed a game keyboard with both hands and feet, and divided the D key and F key into pedal mode, which can be said to be a keyboard specially designed for LOL players.
That's it, isn't it strange?
