How to rotate a selected number of vertexes using the end vertex as the pivot point? I been  using blender 2.8 and I can't figure out how to rotate a selected number of vertexes around another vertex at the end of the selection. When I highlight the vertexes and then click on the end vertex, the rotation tool is placed in the correct position, but the vertexes are deselected. How do I keep the vertexes selected while placing the rotation tool?
Change the Pivot Point to Active Element :


The last selected vertex/edge/face (which appears white) is now the pivot point of the transformations.
