Want to search the Drupal API directly using the Chrome Omnibox?
Right click on the omnibox in chrome (URL box) and select "Edit Search Engines".
You very likely already have a Drupal API search engine entry in the table, but if not, scroll to the bottom and add a new entry with the following items.
- name: Drupal 7 API
- keyword: dapi
- url: http://api.drupal.org/api/search/7/%s
Now all you need to do is type "dapi hook_init" to search the api site directly.
