Non-US backslash
Provided by the ASK Keyboard Dictionary
Non-US backslash is a term used by QMK for the key that is immediately right to an ABNT2 or ISO keyboard's left shift key (ie, would be underneath the right side of an ANSI-style left shift key). Its name refers to what the key's unshifted function is on UK English keyboards (\). In QMK, the keycode for NUBS is KC_NONUS_BACKSLASH and KC_NUBS.
