Hasta La Motion!

I am in the process of learning to write expressions and am wondering how I view all parameters of a node. I know I can view some of them by hovering over the words in the properties bin but is there some sort of API that just lists all of these out? What makes me ask is I am asuming my read node has a parameter color.r but I have no way of confirming this. The Reference guide isn’t quite what I am looking for I want something more syntactical. For example, rather than just showing that a format parameter exists I want to know what form it should be written in.
