I've seen this <http://emacs.stackexchange.com/questions/14320/org-mode-links-open-in-new-tab> discussion, but it doesn't really answer the question of how to have a link upon export to HTML do a :target _blank (new tab). The given answer
#+ATTR_HTML: :target _blank works exactly once -- for the link immediately following where you've stuck it. Additional links thereafter do not get new tab behavior. Any way to tell the whole file to do new tab upon left click of link? LB
