Sure there is an easier way, but I have mine as one of my bookmarks/favorites.
I usually have to click on it from my favorites, which takes me to that page, highlight the address, rt click and 'copy', then click 'back' until I get back to the post, and the 'reply' and then rt click once again and 'paste'.
Never claimed to know chit about this 'puter stuff.
Now, see if it works.
