libtmux:paste-buffer

Paste a named or top buffer into PANE; return a COMMAND-OUTCOME. Newlines become Return by default. RAW preserves newlines; SEPARATOR explicitly replaces each newline with literal text and is mutually exclusive with RAW. VERBATIM preserves every byte, implies RAW and disables tmux's newer control-byte sanitization; it cannot be combined with a separator or bracket markers. BRACKETED uses bracketed paste when the pane enabled it. DELETE removes the selected buffer afterward. Tmux may accept without sending when input is disabled; success does not prove application consumption. Signals STALE-TARGET or an operational condition.
