We find this to be a bit hit-and-miss - sometimes the prompt shows and
sometimes it doesn't. I normally turn on the XO while either holding
down the Esc key or tapping it repeatedly. Is there something more
reliable? I am trying to get a remote (non-technical) teacher to do
this, so it needs to be easy.

I forgot to mention another thing - this is for XO-1.1s (XO-1s with an
XO-1.5 style trackpad).
