 **Note 3: on Wayland, make sure that the `XDG_CURRENT_DESKTOP` environment variable is set, or Makima won't be able to use application-specific bindings.**

 ### Layout hotswapping
 To declare multiple layouts, similarly to app-specific bindings, put `::<int>` at the end of a config file, where `int` is an integer value between 0 and 3, representing the layout number. If not specified, Makima will assume 0.\
