Rect Transform limits vs position and size
I am confused about a really basic element of a Rect Transform Component. When does it show position and size vs. limits. A default button is a perfect example. If you create a button in an empty scene the "Button" Rect Transform looks like this showing position and size:
While the default child text Rect Transform component shows limits left, right, top, bottom. It looks like this: 
My basic questions are:
What determines if the editor shows Position/size or limits for a given Rect Transform component?
With the text, what units are limits (top, bottom, left, and right)? It seems odd they default to all zero.
Yet the text fully fills the button space.
OH! I get it. It depends on the positioning icon. "Center Middle" leads to position and size. While "Stretch Stretch" gives you limits. :-D
