Want to see what she's typing?
Go read her post. (I think "FC" means facilitated communication.)

Oh, and incidentally she doesn't typically type in that position. Her post explains why. In the comments thread we find...

I was mainly typing in that position so my head wouldn’t be blocking the screen, normally I use the computer either from my wheelchair or the beach chair I bashed into and knocked over (that was the loud clatter) in the video. (The beach chair being for when I have trouble sitting upright.) [The post explains why she shows the monitor to the webcam.]
