I just tried it with Emacs's `master` and `C-h o seq-first RET` tells me: seq-first is a compiled Lisp function in =E2=80=98seq.el=E2=80=99. =20=20=20=20 (seq-first SEQUENCE) =20=20=20=20 Other relevant functions are documented in the sequence group. Probably introduced at or before Emacs version 27.1. =20=20=20=20 Return the first element of SEQUENCE. -- Stefan
