there's a technical way an easy way
so i know this isn't the quickest but i use it as it's easier and i've got in the habit now
1) hi-lite the link required
2) right click+copy ( ctrl+c shortcut)
3) in your post type the desired text you want the link to say etc along with any message etc
4) hilite the text you want to use for said purpose
5) with the text hilited select the link icon
6) right-click then paste the link text into the pop up window ( ctrl+v shortcut)
7) press ok
Yes but auto though, rather than doing it yourself.
where's the fun in that
