Center points are selectable
I was making a mess of newspaper ads (as in a lot of them, not messy ones (debatable))  just now when I again encountered some annoying behavior that’s plagued me the three years I’ve been using AI. I would select an object or objects that happen to be within a larger path. In this case that means some type inside of an ad border with no fill. Selecting the text would sometimes also select the border, even though my marquee selection didn’t touch the border; even though the border had no fill. I finally realized that I was also selecting the Center Point of the border which the type I was targeting just happened to be over. The center point is selectable! But there’s no anchor there, right? Just goes to show that to truly get the most out of Illustrator you need to really dig in and understand how it thinks. It’s often not doing what you think it is, or should. Snap to Point is another good example. I just found out from watching an episode of Fridays with Mordy (which is live right now. Damn.) that Snap to Point doesn’t mean any point on your selected path will snap to another object’s point when you move it. Instead it means that the “point” where you grab an object with your cursor will snap to another object’s anchor point when you near it with your cursor. Anyway, gotta get back to work.
