A revert of this CL (patchset #1 id:20001) has been created in
https://codereview.chromium.org/2443303002/ by dmazzoni@chromium.org.

The reason for reverting is: http://crbug.com/653330 This shortcut
conflicts with some web pages, and there's
no consensus on the proper fix (let web pages
override, or switch to another key).
