This is a new CLI action that prints an option or keybind's help documentation to stdout. ghostty +explain-config font-size ghostty +explain-config copy_to_clipboard ghostty +explain-config --option=font-size ghostty +explain-config --keybind=copy_to_clipboard The --option and --keybind flags perform a specific lookup. A string passed as a positional argument attempts to look up the name first as an option and then as a keybind. Our vim plugin uses this with &keywordprg, which allows you to look up the documentation for the config option or keybind under the cursor (K).
