No, that "button" in the middle is B2, as anyone from the original days of the 3-button mouse knows. The perversions that Microsoft foisted on the masses aside, on a real three button mouse, the buttons are numbered 1 through 3, from index to ring finger. The bastardized Microsoft 2-button mouse has no canonical mapping to the 3-button variant.
