IMPORTANT: “The Pen Tool takes on different forms depending on what you’re doing when you’re using it.”
In my work and searches this is the best, if not the only simple explanation of how to use the Pen Tool. The entire post shown here is very comprehensive, a must for learning the Pen Tool in Photoshop, Illustrator, and other Creative programs.
Keep in mind Pen Tool shapes and positions have changed between software versions and are different for various software companies. None the less, the POINT of the pen, the tip, is the position of the line. In Adobe and other programs you can set a “Cross-Hair” style tip point.
Most do not need to memorize what each of these mean or do. Knowing there are differences as you work is an important “path” to using the complete tool set for learning on-the-job.

For those who see the pen tool only in the tool bar, this screenshot shows SOME variations. If you understand these possibilities before using the basic tool, the concept of drawing can be simplified.
(Even this chart might not include all variations for the creative programs. There are selection arrow variations also. If you are aware of a link that shows ALL TOOL variations please add a comment. Thanks).
