FF’s opposite

REW

["Think of the button you’d press to go backward in a video or audio player, often paired with its counterpart."]

"FF" is shorthand for "fast forward," a common button on media players that skips ahead. Its opposite function is "rewind," which moves backward—shortened to "REW" in the same way. The clue plays on tech abbreviations, assuming familiarity with VCR or digital player controls. So, "FF’s opposite" neatly points to "REW" as the three-letter answer.
