title: How to list all the tags searched by cscope?
body: <p>I just need a function just like <code>tags</code> that will list all the tags match my search. But after i checked the document, i still can't find the correspond util to provide this function. So it's will become very unconvinient after i used <code>cscope</code> jumped to one tag and found that this is not the one i needed, and i want to check another one. I have to search again.</p>
