shortcode debugger

Hi Kriesi Gurus
I followed your instructions for Enable Avia Layout Builder Debuggin and I added this:

//set builder mode to debug
add_action(‘avia_builder_mode’, “builder_set_debug”);
function builder_set_debug()
{
return “debug”;
}

to my child theme functions.php, but am not understanding where I can see the shortcodes on the advanced layer builder. Sometimes when I go to the default editor the codes are there, but mostly not. Can you help me out? Opens up so many possibilities!
thanks!
Nancy
