The SR button refers to the right shoulder button on the Joy-Con, when it is detached from the Nintendo Switch. It serves as an equivalent to the R button, acting as a shoulder trigger. In Ultimate, it is used for shielding attacks, much like how the R button is solely used for shielding in Super Smash Bros. for Nintendo 3DS. It is present on both the left and right Joy-Con controllers. The phrase "SR" can be assumed to be an acronym for "Side Right".
