+Terminal multiplexer. [Ghostty](/terminal/ghostty) runs nothing but tmux, and Ghostty's `ctrl+shift` chords are tmux bindings. tmux is also used through the kitty tmux host and remotely on goliath.

 ## Options
 
-The prefix is the default `ctrl+b`.
+The prefix is `ctrl+space`; `ctrl+b` is `prefix2` (the byte Ghostty sends).
 
 | Option | Value |
 | --- | --- |
-| `default-terminal` | `tmux-256color`; `xterm-kitty:Tc` override; features `RGB:usstyle:hyperlinks:clipboard:extkeys` |
-| `extended-keys` | `always`, format `csi-u` |
+| `default-terminal` | `tmux-256color`; `RGB` override for every terminal; `clipboard` feature; `extkeys` for xterm-kitty |
+| `extended-keys` | `on`, format `csi-u` |
 | `base-index` / `pane-base-index` | `1` / `1`; `renumber-windows on` |
-| `status-position` | `top` |
-| `allow-passthrough` | `on` (kitty graphics for yazi previews); `TERM`, `TERM_PROGRAM` added to `update-environment` |
-| `set-clipboard` | `on` (OSC 52) |
-| `mouse` | `on` |
+| `status-position` | `top`, `status-interval 5` |
+| `allow-passthrough` / `set-clipboard` / `mouse` / `focus-events` | `on` |
+| `update-environment` | `TERM` and `TERM_PROGRAM` appended, so programs see the outer terminal (Ghostty/kitty) |
 | `mode-keys` | `vi` |
-| `set-titles` | `on`, `set-titles-string "#T (#S)"`, `status-interval 1`, `automatic-rename on` |
+| `set-titles` | `on`, `#h:#W` |
+| `automatic-rename-format` | `#{window_icon} <label>`: Nerd Font icon, then the dynamic label described under [Window tabs](#window-tabs) |
 | `history-limit` | `50000` |
-| Styling | `status-style` and `popup-style` use default bg; popup border rounded, `fg=#5c5c66` |
+| `detach-on-destroy` | `off` (killing a session switches to another instead of detaching) |
+
+These settings are what [yazi](/tools/yazi) needs inside tmux. `allow-passthrough` carries image previews through to the terminal, `set-clipboard` copies paths via OSC 52, and the two environment variables let yazi detect the outer terminal's graphics support. Nothing binds `M-[`: tmux would read the `ESC [` that starts yazi's terminal-query replies as that key and break yazi's capability detection.
 
 ## Keybindings
 
-| Key | Action |

+## Window tabs
+
+The status line copies kitty's tab bar (`tab_bar_style powerline`, `tab_powerline_style angled`). The current window is an accent-tinted plate with accent text. The other windows use `bg=default` and muted text, so the terminal's transparency shows through them, as with kitty's `tab_bar_background none`. As in kitty, a solid arrow leads into the current window and a thin one sits between two inactive windows. The arrow into the current window is its notch, drawn with the inverse glyph `U+E0D6` in the plate color, which keeps the notch transparent. The session name is an accent pill on the far left (`status-justify left`); its arrow points straight into the first tab, so the pill and tabs read as one chain of arrows. The right side shows `COPY`/`PREFIX`/`ZOOM` flags and the hostname.
+
+Colors are the user options `@tab-bg` (the session pill's text), `@tab-fg`, `@tab-active-bg`, and `@tab-active-fg`. `tmux.conf` sets cyberdream defaults, then sources `~/.local/state/omarchy/current/theme/tmux.conf` if it exists. Omarchy renders that file from `~/.config/omarchy/themed/tmux.conf.tpl`, using the same derivation as the kitty tab bar (active background = accent mixed 20% into background). On a theme change, the `theme-set.d/tmux-tabs` hook re-sources it into the running server, so the tabs recolor like kitty's.
+
+### Tab labels
+
+Each window reads `<index> <icon> <label>`, updating as you work, the same rule as kitty's `tab_bar.py`:
+
+| Pane runs | Label | Source |
+| --- | --- | --- |
+| `nvim`/`vim`/`hx`/`helix`, editing a file | The file name | The title nvim sets (`<file> \| <org/repo>`, astrocore `custom_title`), read from `#{pane_title}` by the format itself, so a buffer switch relabels the tab immediately |
+| Anything else, or an editor with no file | Repo the cwd belongs to (walks up for `.git`); the directory name outside a repo; `~` at home | `tab-label.sh`, run as an async `#()` job. When its output differs from the current name, it re-arms `automatic-rename` so tmux relabels right after a `cd` instead of on the next keystroke |
+
+Labels longer than 27 characters end in `…`. The icon comes from tmux-nerd-font-window-name.

+resurrect saves sessions, windows, panes, cwds, pane contents, and a default set of programs (nvim, less, man, …). Keys: `prefix C-s` saves, `prefix C-r` restores. continuum saves automatically every 10 minutes. When a tmux server starts and no other tmux server is running, continuum restores the last save. In practice that means the first Ghostty window after login or a reboot.
