Set xyz-position of a single vertex How do I do this? I want a little menu like when you move a whole object with an absolute x y and z value for the position of the vertex. I want to move a vertex to exactly be on (xyz) (1.5, 0, 1.5).

I Found this thread online but it's not clear what they mean and the shortcuts don't seem to work anymore on blender 2.8: https://www.blender.org/forum/viewtopic.php?t=19327 (what is the N-key panel and how do I open it?)
This is very easy to do.
You can adjust the vertex position in the Transform panel.
Just type the values into the x,y,z fields.



If you cannot see the Transform Panel, it's in the Sidebar.
