title: copy the word when searching in emacs
body: <p>Is there any tricky ways to do this: in my text files I have a list of words, one word a line. I want search the word <code>new-word</code> in the lists with <code>C-s</code>. In order to search it I need to type the word in the <code>minibuffer</code>, if the <code>new-word</code> isn't exist in the lists, I want to insert it in the list. It seems that I have to retype the word in the <code>normal buffer</code>, is there any ways to remember the word that I have just typed in the <code>minibuffer</code> and copy it into the <code>normal buffer</code>? </p>
