I've seen a couple of PDFs which have come of their bookmarks ("index" tab in most viewers) set either in italics, bold or both.
Googling around I found that the bookmark
package is supposed to do this (I even used its \bookmarksetup{startatroot}
command to have a bookmark to an unnumbered chapter before the first part of the document appear as it should) but I find the documentation a bit confusing.
I tried setting the style for the bookmarks with either
\bookmarksetup{italic}
and
\bookmarksetupnext{italic}
but it seems nothing happens.
Maybe it's a viewer issue (I'm using Evince 3.2.0 under Ubuntu right now).
Has anyone succeeded in this? how so?
