Press ALT+E together, then press B.
1Ctrl+Shift+O opens the bookmark manager in newer versions of chrome.
2Alternatively, hit Ctrl+T and enter chrome://bookmarks
For Macs: Cmd+Option+B
For PCs: Ctrl+Shift+O
For my own reference, I'm using a Microsoft keyboard with a Macbook, so it's Windows+Alt+B for me. This is an old question, but it kept coming up whenever I looked for the answer. So it might help others, too.
