As explained in this earlier hint, you can copy and paste into and out of the latest Safari's Downloads window. But this trick gets even more interesting if you have multiple URLs in your clipboard separated by carriage returns! For example, pasting:
http://www.apple.com/switch/stories/images/ellentop07242003.jpg
http://www.members.shaw.ca/envirogrrll5/ellen.gif
will start two new downloads! I used to have WebDevil handy for its useful "Batch URL Download" function ... thanks again Safari!
