The Chrome menu is the three-dot button at the top right of the browser on Windows, Mac, Chromebook and Android. Google's help pages call it More. It holds settings, bookmarks, history, incognito windows and the update check under Help, then About Google Chrome. On iPhone and iPad, Google's steps just say to tap More.
You can skip the menu for some jobs. Type @bookmarks or @history in the address bar, press Tab or Space, and search. Ctrl + Shift + n opens a private window on a PC, or ⌘ + Shift + n on a Mac.
Google is also testing a redesigned menu with a working search box in Chrome Canary, its nightly test build. It finds commands, bookmarks and recent sites, grouped by type. There's no date yet for regular Chrome.
