I've been using a number of different writing programs recently, and each time I make a switch I always run into the same problem, how to easily insert citations. Most recently I've been satisfied with Sublime Text and this plugin that reads my .bib file and easily inserts the pandoc citation. Now I'm fiddling with Ulysses, and I've run into the problem again: how to easily access and insert my citations. I plan on continuing to use a .bib file and convert with pandoc.

Since I use Launchbar, I thought that if there were a way to search through my .bib file with that and insert my citation, this would make the issues disappear. However, I'm really not sure how to do it. Essentially I'm looking for the same functionality of that plugin just not tied to sublime text. Any thoughts would be appreciated! 

One related problem I run into with other options, is that I often have one author with multiple books which can make searching through citekeys difficult. For instance I may have 5 cite keys listed as @foo123, @foo345, @foo678, etc. So if, when searching, it could display the author name and book, and then insert the citekey that would be the best!

PS I've seen some options such as this one by David Sanson which uses bibdesk, and this one which uses text expander, both of which I've found a little awkward.
