macOS Notes
M- bindings (e.g. M-c, M-t, Alt+T) require your terminal to send Option as Meta/Esc+.- Ghostty / cmux:
macos-option-as-alt = left (managed in dot_config/ghostty/config)
- iTerm2: Preferences → Profiles → Keys → Left Option:
Esc+
Ctrl+1..9 and Ctrl+0 require CSI-u terminal support (Ghostty, cmux, Alacritty, Kitty).
