I am a big fan of keyboard shortcuts and love the way you have incorporated them so you don't have to press the Alt key all the time to access them (I especially like using the context sensititve key on my keyboard - how sad am i)
I would hoever like to be abel to tab down the Metadata section to get to the button to search for metadata - i find when you tab you get stuck in the summary section which is fine when you want to enter information however most of the time this has already been done - anychance of getting a specific Alt plus underlined button to jump to the buttons at the bottom of the window please
