 | File | Purpose |
 | --- | --- |
 | `tab_bar.py` | Provides `draw_title` for `{custom}` in the tab template. Title is `<index> <icon> <label>`: the label is the git repo root name of the tab's cwd (walks up for `.git`), or the file nvim is editing (parsed from nvim's title). Icon comes from the foreground process cmdline (editors, AI agents like claude/omp/opencode/codex, git tools, docker, herdr, tmux, yazi, btop, atuin, ssh, chezmoi, …) with a folder fallback. Labels are elided at 28 chars. No subprocesses or timers. |
-| `pass_keys.py` | Bound to `ctrl+h/j/k/l`. If the window's foreground process matches `vim`, `nvim`, `fzf`, `tmux` or `herdr`, the key is forwarded; otherwise kitty moves to the neighboring window. |

 | `navigate_kitty.py` | No-UI kitten that calls `neighboring_window` with a direction argument; the counterpart nvim can invoke. Not mapped in `kitty.conf`. |
 | `select_tab.py` | Full-screen fuzzy tab picker using `kitty @ ls` data; shows cwds zsh-style. Keys: Up/Down/PgUp/PgDn scroll, Enter selects, typing filters, `ctrl+c`/Esc quits. Not mapped in `kitty.conf`. |
 | `switchtab.py` | Focuses the tab whose `vt` user var matches the argument, or launches one with that var and reorders tabs by `vt`. Not mapped. |
