The problem is not in cutting-and-pasting at all. If I make a presentation, people won't mind cutting and pasting on my computer while I talk. But as long as it is only supported by Adobe >= 6, it's only suboptimal. :( If someone could hack the plain TeX macro, it would probably do exactly what I would expect it to do, but it doesn't sound easy at all. > But that certainly works better on Apple's Preview.app, and probably is > mostly appropriate for the intended use...

Tu sum it up: - the adapted plain TeX trick with boxes doesn't place any content, but only works for plain text (not useful) - \startproperty[mysecret] hides the content (works satisfactory in that view), but only works on Adebe Acrobat, not even in the Wiki - \startproperty[hidden] works on more browsers, but has the same effect as making fonts transparent: it doesn't influence any rules, figures, ... only fonts. For those complaining that hiding doesn't work on other PDF viewers: Adobe also gives up (one of those nice "undocummented features", one could also call them bugs) if I try to save the resulting file as TXT. I just wanted to check if the hidden content will be saved, but I didn't manage to save anything anyway. Thanks for all the comments, Mojca
