It only works with Symbols as a way to quick to edit Symbol Attributes (not Text/Mtext/Ptext inside a symbol). If your cursor is over a Symbol that contains symbol attributes when you use the code, it will invoke the Edit Symbol Attributes dialog (the same is the command found in the symbol browser options or when your Ctrl+Right click on a symbol, Symbol Tools, Edit Attributes. If there is no symbol with attributes, then it looks for Text/Mtext/PText in the drawing to change the contents of. Hope that makes sense. I get confused just trying to type this stuff sometimes
