In windows opened by netssh multi, prefix S toggles broadcast for all panes and prefix e excludes the current pane (a pane-level synchronize-panes off, shown as [SOLO] in the border) or includes it again. netssh sync --pane does the same from a shell. S and e are unbound in a default tmux (E would be "spread evenly"). netssh writes the bindings to a small tmux config and sources it, binds a key only if the user's tmux.conf does not use it (netssh's own earlier binding is refreshed), and the bindings act only in windows marked @netssh. multi.sync_key and multi.solo_key change the keys or turn them off (none); also in the configurator. zellij syncs whole tabs only, so excluding a pane is tmux-only. testenv: the render test presses the keys through the xterm client (send-keys -K) and checks [SOLO], that broadcast skips the excluded pane, that S toggles, and that other windows are unaffected. The client gets GNU grep: BusyBox grep -oF counted only one match per line. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
