Hello Wolfgang or Hans?

Can one of you help me please. Iwant something like this:

\setuppapersize[S6][S6]

\setupinteraction[state=start]

\setupcolors[state=start]

\starttext

Here is an example: by saying

\type{\tooltip[left]{Example}{Is it nice}}, we get

\blank

\midaligned{\tooltip[bottom]{Example}{Isn't it nice?}}

\blank

This file when opened in Adobe Acrobat will show the tooltip "Isn't it nice?" when one hovers over the word "Example".

\blank

\midaligned{\tooltip[bottom]{an example}{Isn't it nice?}  of tooltip on the bottom}

\blank

\midaligned{an example of tooltip on the \tooltip[right]{right}{Isn't it nice?}}

\blank

\midaligned{\tooltip[left]{an}{Isn't it nice?}  example of tooltip on the left}

\stoptext           

But i would need it for footnotes in pdf. Is this possible, or do I have to define somehting?

Thanks

Uschi
