please use turbo mode type a word that contains that string. if there's no word that contains that string, type "none". the screen will flash green if that is a valid word, or you typed "none" if there are indeed no words with that string. the screen will flash red if you did not type a valid word, or if you typed "none" if there are words with that string. type "search __" to check whether a word is in the dictionary. the screen will flash green if it is, and it will flash red if it is not.
