[OS X TeX] How to interrupt a list?

[Louis Talman]

I'd like to "interrupt" and enumerated list to typeset a paragraph  
with the same margins as the text surrounding the list, then drop  
back into the list.  I'd rather not have to redefine the counters  
every time I do this.  Is there a way to override the margins set by  
the list structure and then return to them?
