convert tri's to quads

hello all,
I am new to the forum and blender. I apologize if I am posting in the wrong forum.
I saw an old post in the zbrush forum that mentioned that there was a “killer” script in blender to convert a tri mesh to a quad mesh, but I can’t seem to locate it. Your help would be much appreciated!

Alt+J in edit mode.

Support forum is below. Modeling would be appropriate for this.

There used to be a script (think it was replaced in 2.46) but now it’s Alt-J as stated above.
