right click, that will highlight the address link that you are wanting to link and on that menu that the "right click" has, click copy

Then go to the post you are putting the link into and right click and then click paste.

There are other ways, but, this is the easiest. Be aware that if the address line is very long, then the link will make the post where all readers will have to scroll back and forth and back and forth to read the page that that extra long link is in.

All the posts here, address are not too long and will not cause a problem.

It's when you are posting something from another site that can get you into it being too long and people here do not, me included, like to have to scroll back and for , back and forth to read a post.

You can do an extra long post address link by using this method that Dan has outlined for you, but, be sure all the things you are are EXACTLY correct like the brackets [] cannot be ()... here's how to do that.
