[orca-list] copying all music files

[michael weaver <weavermicha googlemail com>]

i have sort of found out how to use serpentine to copy music 
files to cd.
however i can't seem to be able to select all the files in the 
folder so i end up with just 1 or 2.
> every there any keystrokes in serpentine which i can use to copy 
my music files from my computer to the cd?
i tried control a but orca says nothing.
surely i don't have to use the review keys in orca to go over the 
screen for each track in the folder and try to locate the add 
button every time.
