This page says "Quadro includes a hidden Keyboard for quick text edit and management.
You can recall the keyboard with a single swipe from the bottom of the display-up."
I am going to make a slew of blog posts that are really problem reports against Quadro. "Blog this" is the easiest way I know of to make such reports.
(I used to have a set of weblets that posted such reports to my wiki - but, since I took my wiki down, no easy way.)
