I want to use a latex editor that has auto completion feature for existing references in a latex file. Do you know any good ones? I am trying to find this feature in texniccenter, but I guess it doesn't exist or I could't find it yet.
Update: Ok, I found how to enable auto completion in Texniccenter. I needed first create a project. Then open the file in this project (or copy its text). Now Ctrl-Space inside a \ref{} tag completes the reference automatically.
