Find details of your Contacts with fewer steps using Gmail

1) Consolidate details of your Contacts at a single place - Gmail lets you import contacts (select the Import Contacts link in the left side bar when you're within Contacts) from multiple sources. As it supports importing CSV files from Outlook, Outlook Express, Yahoo! Mail, Hotmail, Eudora and some other apps, you can consolidate all the information about Contacts within Gmail.

2) Configure Gmail Contacts as a search provider within Chrome & Opera- When you normally search for your Contacts, the URL pattern looks like this -
https://mail.google.com/mail/u/0/#contacts/search/%s
.. where %s is the search parameter.

You can use this pattern to configure Gmail Contacts as a search engine option within Chrome & Opera so that you can assign a shortcut to invoke it from the browser address bar.

I've assigned "c" to be a shortcut for  Gmail Contacts. So now, whenever I need to search for a Contact I type "c" in the Chrome address bar, hit space followed by the name of the Contact.

This saves multiple steps while finding a Contact's information
