Ooops. I think I meant the Gizmo. I want to cut it down to use only one point (one vertex) when I use the Gizmo.
(By the way, this is at the point where I have "taken it apart" so this image will never be as a whole in my final project, just certain parts, and not this particular one. I just wanted to illustrate my problem.) Which is that several vertexes are "highlighted" red-yellow-green-light blue, and so if I click on the one to move it, the others will also be moved.
But I need to get it down to just one vertex, highlighted "red", and move that with the Gizmo. (And, later on, I'll need to narrow it down to two, three, four or five vertexes that I can move with the Gizmo. I watched Thom Thom's presentation on the Gizmo, but he typed a key twice, without identifying which key it was, and that is also a problem for me, since I use a mouse).
Thanks for reminding me about the "upload image".
