Just found a great productivity tool for Mac web developers from blogger Mika Tuupola, a native jQuery API dictionary for Mac OS X 10.5. Once downloaded and set up you’ll have access to the documentation within the dictionary, Spotlight searches, and via the contextual info popups in your text editor or Safari. No need to be online to access docs.jquery.com anymore.
Head over to Mika’s site for more instructions and the dictionary download file.
Note: There’s also a similar Ruby on Rails dictionary file available for download.
