I just installed a new copy of MSWord 2007, and it has a nice feat !

You can search for a single ", (in search window: enter " ; click 'find in', select 'Main Document').
Now all quotation marks are marked.
Click on 'text highlight color' (this is the background color or marker color of a letter, not the font color) and select pink.

I use a light blue background, and pink is very good visible, without hurting the eyes.

I don't know for any other word out there, but on MS Word 2007, all quotation marks are permanently highlighted, which helps finding them in the text.
You can very easily remove the color at the end of the job.

There are 3 quotation marks you can select,the standard one ", a beginning and ending quote(curling right up, and left up).

Do the process for all 3 quotation marks and it will make your life so much easier!!

I just finished a 75.500 + words book,with a few thousand quotation marks..
It's hard, but the color makes it jump out the document better, and correcting them isn't as painful as before!
