herdr

herdr is a tmux-like, agent-aware terminal multiplexer that runs inside WezTerm. It owns both tab and pane control, so WezTerm keeps only its fullscreen toggle (Shift+Ctrl+n) and everything else is driven through herdr's prefix key. The config lives in home-manager/herdr/config.toml (deployed to ~/.config/herdr/config.toml).

The prefix is Ctrl+a — press it, release, then the action key:

Action	Key		Action	Key
New tab	Ctrl+a b		Split right	Ctrl+a v
Close tab	Ctrl+a x		Split down	Ctrl+a s
Previous tab	Ctrl+a u		Focus pane ←	Ctrl+a h
Next tab	Ctrl+a i		Focus pane ↓	Ctrl+a j
Zoom (全画面)	Ctrl+a n		Focus pane ↑	Ctrl+a k
			Focus pane →	Ctrl+a l
			Close pane	Ctrl+a d

Other herdr defaults still apply on the same prefix (e.g. Ctrl+a q to detach, Ctrl+a ? for help). Run herdr --default-config for the full list.

Usage

herdr                       # start / attach a session
herdr --default-config      # print the full default config (all options)
herdr server reload-config  # reload config.toml without restarting

After editing the herdr config, apply the dotfiles (home-manager switch) and run herdr server reload-config to pick up the changes.
