Using RH10 - what's the easiest way to create and save HTML code as a snippet for later re-use?

I am using RH10 to maintain and update several WebHelp projects for customer-facing Internet applications. I am noticing inconsistencies in css and html so I would like to create several snippets for later re-use.  My wishlist, so far:  FAQ page with internal bookmarks, product image with table of callouts, and basic page template with corporate header and footer. What's the easiest way to save / export a page that I want to use later as a snippet? Thank you.
