Returning to previous screen

Sometimes in Logos I will click on a link and it will transform my carefully thought out layout. For instance, today I searched for "cut off" and I found an interesting quote in Webster. But once I went there, I did not know how to return to the list of other interesting search finds. How do I click to return to where I was before? Many thanks. (I know that I could have opened the result in a separate window, but once I have clicked on a link, it is too late for that. So, how do I return to my previous view, when I have gone somewhere where I may not want to stay?). Thanks.
