Trying out Opera yet again -- some answers please

Can someone help out here?

When I type opera:cache, I can get a screen that shows a list of cached urls. Unfortunately for me, the urls are "shortened" when long by the use of ellipses (?) so I can't copy several full urls at a time.

Example:
If I right-click on a "shortened" url and copy it via a context menu, I get the full url on pasting somewhere else (text editor or spreadhseet).

https://www.wilderssecurity.com/images/smilies/hush.gif

But if I select by dragging with the mouse and using Ctrl+C, I get
http://www.wildersse ... /images/smilies/puppy.gif when I paste.

I'd like to copy several entries (urls) at a time and so would prefer dragging with the mouse. But I also want the full urls.

Any ideas or RTFM pointers?

I forgot to mention that I'd like to do what I want without resorting to third-party addons.

 

Select them, right click, copy site addresses?
