Snapping lets you easily align UV elements to others. It can be toggled by clicking the magnet icon in the UV Editor's header, or more temporarily by holding Ctrl.
This page is about the Snap header button; for the Snap menu, see UV Editing.
Snaps to grid points.
By default, this option won't snap to the grid that's displayed in the editor, but an imaginary grid with the same resolution that starts at the selection's original location. In other words, it lets you move the selection in "increments" of the grid cell size.
If you want to snap to the viewport grid instead, you can enable Absolute Grid Snap (see below).
Snaps to the vertex that's closest to the mouse cursor.
