Type 'maps' plus a search term into the Omnibox to get places suggestions.
Looking for a place on a map but not sure about the spelling or too lazy to type the whole thing? Suffer no more! Maps Suggestion Box provides geographical names and places autocomplete right in the Chrome's address bar. The same functionality you are used to have in the search field of Google Maps service now can be accessed instantly right in the browser.
