Highlighting Duplicate Words

Joe is an author and he has some ideas for using Word macros to help with his proofreading. One of the macros he wants to build is for finding duplicate words in sentences and paragraphs. He wants to exclude the common necessary words like "the," "a," etc. Joe would like to highlight the duplicate words in a document so he can examine their use and make appropriate changes.

How you go about this depends, really, on how you want to approach the task. For instance, if you want to simply look for duplicate words that are side-by-side, then Word should do that already for you; the grammar checker takes care of marking those duplicate words.

If you, instead, want to find excessive instances of a particular word, then you can use Find and Replace to highlight them. On the Find tab of the Find and Replace dialog box you can enter the word you want to highlight, click the Highlight All Items check box, and then click Find All. Word selects all instances of the Word and you can then use the Highlighter tool to highlight all of them.

Finally, if you want a macro that will step through each paragraph of the document (or each sentence of a document) and look for multiple instances of any given word, then that is a much more complex issue. Stepping through either paragraphs or sentences is not a huge problem; just use either the Paragraphs collection or the Sentences collection in the macro. The bigger problem is dealing with text variations. For instance, does the word "dog" match the word "dogs" or, even, the word "dogged." Without a firm understanding of what, exactly, you want to consider as "matching," your macro can get rather cumbersome.
