I'm finding that I waste a lot of time researching and guessing through trial-and-error what the name of a template needs to be for a given region, node, or block. Is there some easy short cut to empirically discovering this information? For example is there a Drupal function I could stick in block.tpl.php like "print_desired_template_name()" that would dump the name of the block template it's looking for? Drupal clearly knows what name it's looking for, so I bet there's some way to have it print that info and same myself hours of wasted time. Anyone?
