A Handler.t handles a keyboard event by returning a Vdom.Event.t. These should be used as building blocks for keyboard event handlers, for instance to handle a specific set of keys.
type t = Keyboard_event.t -> Virtual_dom.Vdom.Event.tinclude Ppx_sexp_conv_lib.Sexpable.S with type t := tval t_of_sexp : Sexplib0.Sexp.t -> tval sexp_of_t : t -> Sexplib0.Sexp.twith_prevent_default t handles the event using handler t, and additionally prevents the default handler.
val only_handle_if : ?prevent_default:unit -> Condition.t -> t -> tonly_handle_if ?prevent_default cond t handles the event using handler t if cond ev evaluates to true (and additionally prevent the default handler if prevent_default is passed in), and does nothing otherwise.
val handle_by_case : ?prevent_default:unit -> (Condition.t * t) list -> thandle_by_case is similar to only_handle_if, but allows the user to provide a list of handlers and their respective conditions instead of a single one. If multiple handlers' conditions evaluate to true, the first one is used.
