Nicoloco

Hi, I'm new and I just start discovering Affinity. I like it very much so far !! Now, I try to set the interface the way I like to work and I can't find any shortcut to make appearing a flaotting chromatic wheel... allowed me to select new colour while painting whitout having to move back to the colour window every 10 seccond. Is it possible ? Am I looking at the wrong place ? any alternatives ? Cheers
