I use the n52te , the keybindings are just keys on the keyboard . As far as I am aware it does not add extra keys and cannot be used as an extension . So for five boxing I just have the 1 to 10 number keys and the - = buttons . And on the spare n52te keys I have interact with target and follow . Is boxer uses Alt Backspace to follow , this is mapped to 1 key for example .
