As of today, all AdWords advertisers can pause and resume keywords (for keyword-targeted campaigns), sites (for site-targeted campaigns), and ad creatives. As you can see from the picture below, this feature is functionally similar to the pause/resume feature on the Campaign Summary page - we've simply extended it to the keyword, sites and ad variations tabs.
This is yet another example of a new feature based on advertiser feedback. Thanks for your suggestions and keep the great ideas flowing!
