check for duplicates of a word within next 100 words

[sylvio]

Good day,

Please, help me with a macro which can facilite proofreading of texts.
This macro should look for dublicates of every word in all its forms within next ,let's say, 100 words or 3-4 sentences.
There should be also a list of exclusions, like 'a, an, the, with, to' etc omitted from check.
Found dublicates should be highlighted.



Is it possible?
