Is there a Google Chrome extension that acts like Firefox's keyword quicksearch bookmarks?

Solution 1:

Not only does Chrome have this, the browser adds them automatically as you use site's search boxes.

Go into the Options -> Basics Tab -> Manage. You'll see a list of "Search Engines". Some of them are supplied by Google when you install Chrome, others are learned as you use the browser. Double-clicking an entry will let you edit it, where you can change the keyword from the default (domain name) to something shorter or more memorable.

To use your example, I hadn't used imdb.com yet in my Chrome install. So I went there, used the search, clicked "Go", and got my results. After getting back to the "Manage Search Engines" dialog, imdb.com was at the bottom of the list. Double-click it, set the keyword to "imdb" and go back to the browser. Now when I type "imdb" in the address bar, the first auto-complete entry is to search imdb.com. The browser asks to "type Tab to search imdb.com", but I just hit space anyway like I do in Firefox and it works.
