When writing some article in LaTeX you use a statement like this \cite{becker2016sparktrails} to cite your references. Yet, especially when putting together your related work, you need to have a look at the article again. Dependent on how you manage your references, this includes a more or less cumbersome search for the the publication and the PDF associated with the corresponding Bib-Key (becker2016sparktrails).
Now, in case you are managing your publications and references with BibSonomy diligently uploading your PDFs (e.g., using the Chrome plug-in BibSonomy Scholar) in combination with the LaTeX editor TeXlipse, we came up with a little shortcut:
Mark the Bib-Tex Key, hit F9 (or any shortcut), and the PDF will open in your favorite PDF viewer.
To achieve this, we use a Python 3 script to download our references and take advantage of the External Tool configuration and corresponding shortcuts provided by Eclipse. This is a little hacky, but it works nicely in most cases. With a little more programming, this approach can probably be integrated more tightly and even work with other editors as well (such as TeXstudio or TeXmaker).

Have fun writing your manuscript :D
