Word frequency for a specific word?

I know you can check which words are a specific tic of a writer by number of uses (cmd-shift-option-s, then the Compiled tab and a little drop-down menu called Word Frequency on the bottom left of this dialogue box).
But is there any way to click on a particular word and see how frequently it’s used in a document or project?

The Word Frequency option is the best way to do this really. You can do a FInd/Replace with the same word in each field but you could get yourself in a bit of mess if there are capitalized and non-capitalized versions of the word which then get changed, but you would get a count for how many replacements happen. A little more basically you do a find and the find next and count up how many are found.
