 | `prefix o` | Sessions palette ([`tmux-sessions`](../shell/scripts.md#tmux-sessions)): fuzzy-find the other sessions, every window of every session, zoxide's and `~/.config`'s directories, and Rename/Kill items per session. Typed text that is not a session starts one by that name in its zoxide match |
 | `prefix t` | Project Tasks palette ([`pj-palette`](../shell/scripts.md#pj-palette)): install/dev/sync/make/compose quick actions plus every `pj` task. One-off tasks run in a full-width bottom split (25% of the window); dev servers and `docker compose up` run in a background `<session>:<tool-and-command>` session shown in a popup (`q` hides, `ctrl-c` asks `y/n` then stops), listed under Running to reopen |
 | `prefix w` | Workmux palette ([`workmux-palette`](../shell/scripts.md#workmux-palette)), Ghostty `ctrl+shift+a`: tracked agents by status, the repo's worktrees with Close/Merge/Remove, new worktree from the typed branch or a prompt, dashboard, sidebar, last-done. Replaces tmux's `choose-tree`, which the Sessions palette covers. See [workmux](../tools/workmux.md) |
+| `prefix S` | Toggle workmux's live agent sidebar in every session (`workmux sidebar`), Ghostty `ctrl+shift+s`. tmux's session tree stays on `prefix s` |

 | `prefix a` | omp in a background session `<session>:omp` (pane cwd), shown in a popup docked bottom-right (35% × 60%) and listed in the [omp palette](../shell/scripts.md#pj-palette) and under Running in the tasks palette. In the popup, `ctrl-c` hides it and `ctrl-q` quits omp. Inside any background-task popup, `prefix a` hides it too, so `prefix a` toggles omp (no Ghostty chord; `ctrl+shift+a` is the Workmux palette) |
