How do I quit epiphany?

Sorry to be so dense, but I have been unable to find a way to "quit"
all windows of Epiphany.  If I have four or five windows open the only
thing I have found to do is go to each window separately and click
File/Close.  What is the correct way?  Is there a keyboard shortcut?

Thanks for the help.
