I understand that Pluto uses the Ratposing window manager.
This is a very simple window manager with no mouse controls. The window management (window order, max/restore/resize, focus) is controlled via escape sequences typically starting with Ctrl-t.
I got problem the first time that I tried to download a media file from Firefox to test the playing of multimedia in Pluto. I got a maximized download window (the one the usually is small and you can minimize) for as long as the download lasted. The Pluto station was unutilized for 10 minutes (luckily it was not video). I tried to use Ratpoison's escape sequence to trigger a command that would switch me to the previous window. However Ctrl-t was captured by Firefox (instead of Ratpoison) and I was geting a new window tab.
So the question is, what is the escape sequence for Ratpoison control in Pluto? How can I control my windows when in Pluto's Computing mode?
