Macro to highlight text between 2 points in word 2010

[jsilva1950]

I am writing a document in word 2010 and need a macro which highlights from starting point 1 to ending point 2 ( the idea is to see the bottom bar for number of words in the highlighted part). I have made markers by typing xxx at point 1 and yyy at point 2. I am quite new to ms word macros. Can someone pl give me the code ? Tks a lot.
