Use mouse left-click to select mesh triangles.
Finish selecting first Pug's eye.
To unselect mesh triangles: on Windows hold CTRL and mouse left-click, on MacOS hold CMD and mouse left-click.
Tip: Check the box Symmetry and set the symmetry plane to select both sides on symmetrical models.

Step 3 Select 2nd eye
