I am trying to see if there is a way to select a specific word that appears several times in a pdf and highlight each instance of the word with the highlighter tool in preview (adobe will do if necessary). I have each instance of the word select with Preview's "find" feature, but so far have not seen a way to select all instance of the word without going through the search results one by one and selecting highlight. Anyone have an idea about how to accomplish this? Thanks a bunch.
