Mouse buttons / Creo Help

I am new to Creo (parametric 4.0)

I want to know the functions of my mouse button, a simple 3-button mouse with scroll wheel as middle button.

I opened Creo, using the help function, I cannot find a table showing the mouse button functionality.

When I type: "function of mouse buttons" I get "No result"

Typing in a search of "Mouse buttons" I get all kind of irrelevant information.

Al I want to know is how what the buttons do?

Anybody who might have a table of mouse button functions?
