It is always a pain clicking on a link to a journal article only to hit a paywall. It's doubly painful when I know I have institutional access via my library's proxy server, but have to jump through hoops to get it: go to the library website, log in, copy and paste the article name or PMID into its PubMed search box, and finally download the PDF. Arduous, and—turns out—unnecessary.
Enter Alfred 2 workflows. Here's a nice article I found on Twitter today. The NEJM link in the top right corner leads to an abstract, but I need a special archive subscription for the full PDF. No matter—I can just highlight the PMID and hit my special Alfred 2 keyboard combo:

And Bam! The ugly but magic button is where it should be. Your institution might have a prettier one.
To make it clear—this simple workflow will do a PubMed search of any selected text anywhere in OS X, all through your institutional proxy server. Finding an interesting reference while reading an article, highlighting its title, and hitting ^⎇⌘P to get to the PDF always feels like magic.
