What you're asking for isn't feasible, since there's no way for the macro to store the details of the last change. Setting up some logic to change white to black, black to yellow and yellow to white, in sequence, is easy enough. But not going from white to black, black to either yellow or white. Indeed, it's not at all clear what the criteria are for the final black to yellow to be triggered as an alternative to the black to white.

It don't need to remember my last choice, as long as I could use the same button to swith between them.

1 push: Black on white.
2 pushes: White on black.
3 pushes: Yellow on black.

If i push to times quickly, I will get white on black. If I press 3 times, it will be Yellow on black. If I got White on black, and want black on white, It's okey to press one time.

Is this possible?
