No, but for the edit form these are the name="..." attributes in that 
HTML form fields.

If something not documented by Pm or by me, it should *not* be 
considered written in stone.

And if it is, it should be considered written in wiki. ;-)

Also, PHP has been known to introduce deprecations and incompatibilities 
with what previously used to work. Also, the $_REQUEST variable may hold 
a different value from one server configuration to another

Almost. It should be more like this:

   if(@$_POST['postedit']>'') {
     $_REQUEST['preview'] = 1;
