[NTG-context] viewer magnification in full screen (/OpenAction)

Hi, I want to open a document in 'full screen', showing the complete page at maximal magnification. Couldn't find a proper way to set the magnification though. Peter Example: \setupinteraction[state=start]% openaction, focus \setupinteractionscreen[option=max,height=fit] \starttext Full screen, all visible and at maximal possible magnification... \stoptext
