I just talked to Contour and have instructions here!

Allen,
I figured it out! My main problem was that I don’t know Vegas well enough to know what commands I would use the most.
But, I’ve been using the Trimmer and the main keystrokes I use are the I(n) O(ut) and A(dd).
So now, my buttons 2-3-4 are set for I O A.
#1 is single mouse-click.
It just works.
I think I can expand it a bit for other keystroke commands using the Ctrl, ALT, Shift and combinations thereof.
i no longer even need the JKL sequence as the shuttle does it.
ciao,
ken
