-description: Ghostty configuration and its herdr key sync.
+description: Ghostty as a tmux-only terminal — every window attaches to tmux, and ctrl+shift chords drive tmux.

-GPU terminal emulator kept alongside kitty. Its bindings send the same herdr prefix bytes as the kitty herdr host.
+Ghostty is only a [tmux](/terminal/tmux) client. tmux owns tabs (windows), splits (panes), sessions, and persistence. Ghostty draws the text and handles the clipboard and font size.

+## Persistence
+
+Closing Ghostty only detaches from tmux; the shells keep running in the tmux server. Across reboots, tmux-continuum saves the layout every 10 minutes. When the first Ghostty window starts a new tmux server, continuum restores the last save. See [tmux](/terminal/tmux#persistence).

 ## Keybindings
 
-| Key | Action |
+`keybind = clear` comes first and drops every Ghostty default: tabs, splits, `alt+N` goto_tab, and `ctrl+alt+arrow` goto_split. Those chords then reach tmux, which binds `alt+1…9` and `ctrl+alt+arrows` itself. Each `ctrl+shift` chord sends tmux's second prefix, `ctrl+b` (`\x02`), followed by a key.

-| `cmd+n` | New window |
+| `ctrl+shift+c` / `ctrl+shift+v` | Copy / paste |
 | `ctrl+plus` / `ctrl+minus` / `ctrl+zero` | Font size +1 / -1 / reset |
