LaTeX - how to change intra-document link format?

Question

I love LaTeX but can't figure out how to change the red box around linked items (TOC to document detail, glossary entries used within the document) to the standard blue underline that you see most often.

Any ideas how to do this?

Answer 1

(Might be a candidate for migration to the TeX/LaTeX site.)

This answer is part of the way there, but there's a comment below (untested by me) that says

\ifpdf\usepackage[pdftex,pdfborderstyle={/S/U/W 1},hyperfootnotes=false]{hyperref}\fi

should work. If you're working exclusively with PDFs, you can drop the \ifpdf, pdftex, and \fi. See also Wikibooks' hyperref customization section.

Answer 2

This can be controlled by the linkbordercolor option for Hyperlinks. For example:

\hypersetup{
    linkbordercolor={0 0 1}    % uses format {red green blue},
                               % where each value is between 0 and 1
}

should set the default border colour to blue.
