# `/` search on a TERMINAL pane: the same tag input as a file pane, searching
# the shell's own scrollback (the plain text view Look reads, prompt rows
# hidden). Results land in a +Search OUTPUT BUFFER — a file pane with no file
# behind it, so its tag has no Save — and point at `@p1:LINE:COL-ENDCOL` (the terminal's serial), the
# look target that names a live pane, since a terminal has no path. n/N SELECT
# the next/prev row in the buffer and open nothing; Enter — the look chord —
# is what scrolls the terminal to that line of its scrollback and selects the
# span the row names.
#   PLACEMENT, and this script is the proof: an output buffer is NOT a document
# — it is the result list of the pane that asked for it — so even here, with no
# doc pane in the session for it to join, it does NOT take a column of its own.
# It splits BELOW the shell it came from: every snap below stays ONE column,
# the shell's tag and the +Search tag both starting at x=0, thirty rows split
# between them, and nothing shifts sideways.

# right-clicking a word that names no file is the same search (acme button 3),

# so the buffer stays empty. Col 5 row 4 is the `M` of the first `x MARK a`,
# in the shell's body in both modes (normal hides the prompt row, leaving it
# blank, so the output rows sit at the same place either way).
#   The left click first is the price of the step above: it left the cursor in
# the results buffer, and c-b is read by the ACTIVE pane — there is no tty
# behind a +Search to toggle.
