Now, I’m really after something else, but here’s my first Ubiquity scripts. It allow you to select a DOI on any web page (which really only makes sense if it is not already a hyperlink), you hit ALT-SPACE (Linux), CTRL-SPACE (Windows), or whatever the shortcut is on your operating system, and type resolve-doi and it will automatically convert the DOI into a hyperlink to look up the paper.
