Pressing the MID mouse button (½) gives a Segre chart colour coded by integral/half-integral spin, or bosonic/fermionic character. Note the strict chequer-board pattern. Pressing the RH mouse button (P) produces a Segre chart colour coded by parity, either odd (-), or even (+).
By pressing both RH and LH mouse buttons together (S) and (P), then the chart is colour coded by both spin and parity. 'Negative' (-) values of spin code for odd parity, and 'positive' (+) values for even parity.
Other combinations of buttons have no other effects.
