I want to use the pen tool in Adobe Illustrator to make hair strands for a vexel portrait. I have to make hundreds of strands. The problem is that I would like to use the pen tool to make two anchor points (to make a strand of hair) without having to select the selection tool after each strand to make a new one.
Here's a video of what I am talking about: Vector/Vexel Hair Tutorial (Part 1)
Just press "P" after you create a strand and it'll allow you to make a new one. Click, click, P, click, click, P...one hand on the mouse and one hand on the P key makes it pretty efficient.
Your question is a bit confusing since you link to a video using Photoshop, not Illustrator.
However, to temporarily use the Selection tool in Illustrator just hold down the Command key on the Mac or Ctrl key on Windows.
So... Pen Tool, click, click, Command key-click, release Command key, click, click, Command-key-click, etc.
Another option is to use the Deselect All item. When you want to deselect a path simply hit Command/Ctrl+Shift+A.
