Where is the "target max walk speed" green window located?

I am attempting to follow along with the “character movement in blueprints” steps but I cannot find the green window located directly to the right after the blue character movement box. Help?

Its just called “max walk speed”. Those boxes are called nodes and all the little colored ones that dont have white pins or wires are variables. The target pin on the left side refers to which component or blueprint actually has that variable in it. In this case its the movement component. The reason it wont show up is because you need to drag out the blue pin from movement component before searching for it, or becayse youre actually searching for the word target.
