It is baffling, rather than easy.  What did you find in your homework that 
told you that the X11() device had 'pages' and responded to those keys?

I am unaware of any documentation that says otherwise, so please enlighten 
us with the fruits of your researches.

The windows() device has this capability, but it is not enabled by 
default.  I don't believe any of the third-party graphics devices in 
CRAN package do.
