The X-keys XK-4 stick uses MacroWorks 3 software to record key commands from the keyboard and send them to applications on any PC. ControllerMate software for Mac is also included free of charge. Any sequence or combination of keystrokes from standard keyboard may be assigned to any key on the X-keys. Mouse commands (click and scroll) may also be programmed. Simple, intuitive steps allow even non-technical users to program the X-keys instantly. Programming files may easily be copied and shared. The X-keys stick may also be operated in hardware mode, saving all programming in an onboard non-volatile memory and emulating the PC keyboard port (PS/2) version of the X-keys.
