Dune BD Prime 3.0 works well with USB wireless keyboard

I got this cool Dune BD Prime 3.0 combo blu-ray disc and media player without a remote but I got it to work with a USB wireless keyboard.

Here's a list of what I could get to work:

while the player is running:

vol +/- and mute buttons work

ff, rew work

arrow keys and enter

A B C D =f9 f10 f11 f12

select = insert or f4

number keys = track number (type them quickly for a two digit number)

end = return to menu

A = audio sync
D = subtitle on/off (doesn't work unless you first activate subtitles)

menu key on keyboard works to bring up menu (the context menu key next to the right control key)

f5,f6 = angle
f3 = goto time

scroll lock = deinterlace settings

double hit of delete key acts as though you reloaded the disc

ESC = drop out of menu

f1 = info

pause = pause

music button = audio track


I wish every media player would work with a usb keyboard.

It'd also be great if they could add a few more keystrokes to make it more functional and ergonomic, like greater than and less than could do 2x/4x/8x forward/reverse play, s could cycle through available subtitles, spacebar could be play/pause, etc. Just a few additional keystrokes would make a huge difference in usability.
