Usually, when I look at my Address Book, I like looking at the names of companies only. To see the contacts associated with the company, I look at the contacts following window. In some circumstances, I need to find contacts within companies and display them in the main Address Book window.  For example, this would be useful if I want to send a Christmas card to all the contacts from a specific couple of companies, or after I do a search on a company specific user-defined field and I want to select all the contacts from the results.

To do this, do your search and select all the company's from which you want to select the contacts from.

Then go to search, Retrieve Contacts.

This area of the search menu is pretty handy. You can search for Contacts, Opportunities, Partners, and Customer Service cases associated with the companies that you have selected in the Address Book window. Now this is not very useful if you only have one entry that is selected in the Address book because you can get the same information from the following windows. Where this becomes really useful is if you have multiple entries selected.  You can get some valuable metrics just by looking at all the Opportunities, Partners, or Customer Service cases associated with specific companies.  For example, you can see what kind of Customer Service cases are created for all companies in the East region or you can see what kind of Opportunities are present for Companies who only deal in a specific type of Wine.
