We present the principles of the switching of the polarity and chirality of a magnetic nanodisk by external in-plane field pulses. We show that to switch the polarity requires a field pulse of a sufficient amplitude. On the other hand, to switch the chirality requires a pulse with a smaller amplitude and with a precisely chosen duration. Both phenomena together form the full control of the vortex state.
