I'm planning on using Frodoplayer as I can pretty much use it without using a mouse or any kind of pointing device.

The most useful setup I've found is to have the audio player section setup with the 'Directory' view enabled, so I can scroll through albums using up/down cursor keys or page up / page down. I keep all my music categorised by album folders... i.e

e:\music\smashing pumpkins - machina\
e:\music\smashing pumpkins - mellon collie\
e:\music\smashing pumpkins - mellon collie\galapagos.mp3
e:\music\smashing pumpkins - mellon collie\tonight tonight.mp3
e:\music\smashing pumpkins - mellon collie\zero.mp3

Then using just the tab key, i can switch the focus from the directory list to the playlist of that particular album... but this seems to take 3 or 4 hits of the tab key; it must be moving focus to some other objects, and then a further few keystrokes to move back to the directory list.

Is there some way of binding a key to move focus instantly from directory list to playlist, and back again at a second press?
