 "a": ke kiri
 "d": ke kanan
 "w": ke depan
 "s": ke belakang
 "t": toggle depth-testing
 "u" : ke atas
 "n" : ke bawah
 "i" : putar ke bawah terhadap sumbu X
 "j" : putar ke atas terhadap sumbu X       
 "o" : putar ke kiri terhadap sumbu Y
 "k" : putar ke kanan terhadap sumbu Y      
 "p" : putar ke kiri terhadap sumbu Z       
 "l" : putar ke kanan terhadap sumbu Z
