how can i find the selected vertices in uv editing on my mesh?
I want to find these big faces on the right side on my mesh.

The UV Sync Selection (top left with two diagonal arrows) shows all or only the selected ones from the 3D view… Maybe have a look at the manual : https://docs.blender.org/manual/en/latest/editors/uv/introduction.html#interface ?
