- Chrome > Preferences > Default Search: Manage
- Click the + sign
- Choose your name and keyword. I used 'Plone 3 API' and 'api'. Use this beast for the url: http://www.google.com/search?hl=en&q=site:http://api.plone.org/Plone/3.0/private/products/+%s&aq=f&aqi=&aql=&oq=&gs_rfai=
- Save and enjoy.
In my case to use it I just enter 'api PloneModuleName' into the url bar and click enter. This gives me instant gratification and filters out the weeds of versions I don't want. Plone on.
