The current state of a keyboard is queried with the Get condition request (see Maple Bus). The condition stucture for the Keyboard function code ($040) is as follows:

int8 shift          ; shift keys pressed (bitmask)
int8 led            ; leds currently lit
int8 key[6]         ; normal keys pressed

In the following tables, orange colour is used to mark keys that only exist on Japanese keyboards, and blue colour to mark keys that exist on a European keyboard, but not on a Japanese one.
