Ask HN: Is it possible to focus bookmarks bar in Chrome Mac

When I use Chrome/Chromium on GNU/Linux, I am able to focus the bookmarks bar by pressing either Alt+Shift+B or Ctrl+Shift+B or something similar. It puts focus on the first item, which I can immediately activate with Enter (or is it spacebar?) or alternatively I can tab to the next one. This is great for activating bookmarklets, although they're slightly crippled by only working on pages which are allowed JS. However, on Mac, there seems to be no such shortcut. No matter how much I've googled or tried different combinations of all the different meta keys with B, none seem to work. Does anyone know if there is such a thing?
