i've added printable support (was already there but no key available)

\setupinteraction[state=start]

\defineproperty [mojca] [layer] [state=stop]

\starttext

\input ward

\startproperty[mojca]I hate hacking TeX!\stopproperty

\input davis

\button{Show   Mojca's Secret}[VideLayer{mojca}]
\button{Hide   Mojca's Secret}[HideLayer{mojca}]
\button{Toggle Mojca's Secret}[ToggleLayer{mojca}]

\stoptext

the bad news is is that acrobat does not handle it (my guess is that such 
features don't work becausethey have no way of testing it)
