How to grab individual vertex in UV editor? I want to align a line of vertices in a UV map of an object I am modeling, but whenever I try it moves all other vertices connected to them. How do I just select a single vertex while UV modeling?
Selecting a vertex (in this case, two vertices overlapping, but the same applies when I select one)

It selects a vertex (or vertices) that are connected even though I didn't select them
You can disable “Sticky Selection” mode in the dropdown menu to the right of the vertex/edge/face select boxes
