Beginner - Adding a Vertex

Hi, I am going through the blender video tutorials and I am currently on the 6th one. For some reason, I do not think I am adding vertices.

He mentions that the command is Ctrl-Left click (when in edit mode); and that a vertex should show up (and be yellow due to it being selected). When I do this it doesn’t appear that anything has happened.

What am I doing wrong?

EDIT: Figured it out. I guess being in face select mode affects the ability to make vertices? Is this correct?

Ya, you need to be in vertex mode to create vertex.
