No. 

\startJScode{fullscreen} 
  app.fullscreen = true ; 
\stopJScode

\setupinteraction[..,openaction=JS(fullscreen)]

(or, openaction=,{JS(fullscreen),lastpage,firstpage,CloseDocument}]

Alternatively: 

\startJSpreamble {whatever} used now 

function FullScreen 
  { app.fullscreen = true } 

\stopJSpreamble 

... openaction=JS(FullScreen)]

This saves bytes when one uses a function more than once. 

So, it comes down to separate the JS code from the reference; than way
one can more easy replace the implementaion by for instance by PERL code
in a dviviewer than has an interface to perl (Wasn't gilbert working on
that?) or a real Java plugin in the reader (Matthew's next challenge).
