Since some of these references are buried deep within the documents it will be helpful, once within a specific document, to do a search of that specific document.
In the Mac world this is done by clicking on the Command key and F simultaneously and then typing in the word Seton. This will take you to first occurance of the word in that document and thereby save a lot of scrolling.
In the PC world the same can be accomplished by clicking the Control key and F simultaeolusly.
Obviously this trick can be useful in other situations.
