Ghostty Config

This handles Ghostty terminal config file editing with full knowledge of syntax, locations, and keybinding format. It knows about the config.ghostty vs config filename change in 1.2.3, XDG and macOS paths, and the critical gotcha that config-file includes process at file end so later keys won't override included values. The keybinding syntax is well documented, including physical keys, sequences, prefixes like global and unconsumed, and the named key tables added in 1.3. Shell integration coverage is thorough. Use this when you need to set up or modify Ghostty configs and want to avoid the manual's quirks around loading order and keybind format.
