If you’re editing a script that contains a tell block targeting an application, you can quickly open that application’s dictionary window.

• Select anywhere inside the tell block targeting the application whose dictionary you want to open. (This is to put your selection into the desired tell context.) Then choose File > Open XXX Dictionary, where “XXX” will be the name of the application. (The command-key shortcut will come in very handy here.)

  Alternatively, choose Open XXX Dictionary from the contextual menu.
