I included a link in a Stack Overflow question and wanted to edit it. Awhile ago, someone showed me how to make it more like clickable text instead of just a bare URL, but now I can't remember how. I went to the FAQ to find a quick Stack Overflow editing cheat sheet (I'm guessing such a cheat sheet exists), but it's not there. Is there some reason the Stack Overflow FAQ doesn't point to it?
There's the question mark in the upper right hand corner of every textarea (i.e. whenever you post or edit a post). Click it, then click advanced help.
