 * PDF Tools
 
-  [[https://github.com/politza/pdf-tools][PDF Tools]] makes a huge improvement on the built-in [[http://www.gnu.org/software/emacs/manual/html_node/emacs/Document-View.html][doc-view-mode]]; the only
-  drawback is the =pdf-tools-install= (which has to be executed before the
-  package can be used) takes a couple of /seconds/ to execute. Instead of
-  running it at init-time, we'll run it whenever a PDF is opened. Note that
-  it's only slow on the first run!

+  the =header-line-format= gives a very clean PDF-viewer; let's add that to a
+  key.
