If you want access to your full set of Chrome bookmarks, Ctrl-Shift-B will toggle the browser's Bookmarks Bar in and out of view. Any site you've saved into the Bookmarks Bar folder will appear along the top of the screen; a drop-down menu with all of your other bookmarks will be available at the far right.
For a more streamlined look, right-click each site in the Bookmarks Bar, select Edit, and remove its name. This will leave you with a text-free list of icons pointing to your favorite pages.
