Change filename in Preview I end up with lots of screen shots that look like this:



Obviously after a while I do not know what they are.

So I open them in Preview to see, and would like now to change the file name to something meaningful.

How do I change screenshot name while viewing in Preview. 

Or is there a way to name the screen shot at the time it was taken (without auto assigning the file name). Basically, take the screenshot- pause + popup asking to name the file before it is saved, while it is still fresh in my memory what it was.

Right now I have to exit Preview while trying to remember the 


  "§$%&amp;/()?*☂☠


and rename it in Finder.

I can skip the Preview and use Finders Icon or Clover view but that is not the point of my question.

Edit: My Preview must be broken since I do not have the Pull down popup



Preview Version 7.0 (826.4)

MBA 10.9.5
I am using Yosemite (10.10) but I believe this feature has existed for a long while...

Simply open the file in preview and click on its name at the top of the preview window.
