I like the answer from dreeves and the handy search he suggests too. I don't have the Stackoverflow "rep" points to comment, but...

Since lines in raw *.tex tend to be very long, the output from grep can be overwhelming (i.e., entire paragraphs); I suggest a variation to only display the words ending in '[A-Z].' (followed by one or more space, followed by a new capitalized word). It is,

grep -o -E '[A-Z]+\. +[A-Z]+[A-Za-z]+' *.tex
