SolidWorks 2010 Detail View Circle Text and Arrows

Can anyone explain, specifically, how to change some of the parameters of a detail view?  As you can see in the attached image, the arrows are (IMHO) too small and butt right up against the letter.  I'd like to make them larger and add some space between the tips of the arrows and the letters.  I've been all through the document property options and have not seen anything that affects these two issues.
