Just a standard copy and paste will do the trick.
First, you'll need to find and copy the address of the link, ---- http etc.
If the link is on a web page, do a right click (or whatever is your screen reader iquivolent), to bring up the menue with copy, paste, save targit etc, and select copy short cut.
If the link is in your favourites menue, you can either do right click iquivolent, or use the properties key (also called thee application key), at the bottom right hand corner of your keyboard next to right control to bring up the menue with copy, paste etc. Select properties to bring up the address, then copy it with ctrl C.
Which ever method you use, once you've got your coppied link address, just paste it here with ctrl V.
you can use Bb code to make it look slightly more tidy, --- Eg, having a "visit this link" message instead of a long http web address, but this is just for appearences really.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
