vakayu, if it's any help
highlight the link you want to copy (probably starts
http, the address at the top of the page) - left-click and hold the cursor down while you drag it across the address, or else just click about three times within the address and it should come up highlighted in blue.
control+c (that is, hold the control key down while you click on "c")
go to wherever you want to put the address, eg the answer panel on an AB page like the one you typed yoru answer in
control+v (same way as for control+c)
and it should copy.
