Keyboard access to current folder dropdown in 2013?

In R2012 there was keyboard access to the current folder drop down on the toolbar (alt-r) which I found very useful.

In R2013 the current folder GUI widget is now much wider so even more inconvenient to access with the mouse (ie to select a previous working directory) and alt-r seems to no longer work.

Is there anyway to get keyboard access to the list of recent working directories? (from the command window would also be fine).
