If you want is to make the Bookmarks visible (i.e. the cross-references to a
bookmark). Turn on the option Field Shading to Always (this is under the Word
Options, View), all the cross references and any other fields in your
document will now have a grey shading.
If you want the Bookmark itself to be visible, turn on the Bookmarks option
in the Show section, now the Bookmark square brackets will be visible.
The above is described as for 2003 as I don't have 2007, hopefully though it
will point you to the right place.
Now if you you want to apply a style, at least you can now see them.
I don't think there is a Find/Replace option to do what you want. Maybe a
macro guru can add a programming solution.
Hope this helps

Hi all. I'm using Word 2007 and I would like to change the style of
all the bookmarks in my document. Is there a standard style that I
can tap into to change the look-n-feel of all my bookmarks at once?

Thanks
