*NOTE*
YOu have to have that LOUD.LSP loaded already...
This is also assuming that you have an existing box around your text. (if you don't, you should make another macro without the erase command in it) That's what the erase command is for...so you can erase the current one. Then, you edit the text and right after, LOUD draws the new box around the text you just edited. Make sense? It's not as reliable as a properly tested, full blown lisp routine, but it's the best I can provide with my complete lack of lisp writing skills.
