Assemblies often carry several names for the same sequence. Hover the information icon beside the position to see the alternatives, such as 17, CM000679.2, and NC_000017.11 for human chr17. Any of these names will work in the position box and in your own custom tracks, hubs, and bigBed or bigWig files, so there is no need to convert first.
