The attached file presents my latest ideas on tooltips,
with some tests (in Italian, but even if you don't
understand what's written, it doesn't matter). The only
point is: displayed formulas don't work. Any ideas on why?
(the relative text is commented out).

Ecco del testo con un mio \gbtooltip[middle]{tooltip}{Questo tooltip dovrebbe avere
un rettangolo con dimensioni circa in rapporto due ad uno}; facciamo
\gbtooltip{ancora una prova}{\switchtobodyfont[small]
Stavolta con qualcosa di molto più lungo; e perché no, mettiamoci
anche una formula, $x^2+y^2=r^2$, tanto per vedere come si comporta il
\TeX\ in queste situazioni~\dots\ sembra che si comporti molto bene;
allunghiamo ancora per essere sicuri che il rapporto 2:1 (in effetti minore)
vada bene anche per testi molto lunghi. Sembra non dare nessun fastidio~\dots\
e se lo definissimo \tex{long} ed usassimo un \tex{par} in mezzo, come sarebbe?
Non possiamo perché \CONTEXT\ definisce \tex{definesymbol} come non-\tex{long}.
Hm. Comunque, questo testo è posizionato vicino al bordo della pagina; sembra
che AcroRead non se ne curi, e sposti la finestra per farla rientrare nell'area
visibile; ora faremo qualche esperimento a zoom diversi per esserne sicuri.
No, pare di no. Se è troppo grosso va fuori. Bene.}; infine ne facciamo un'altra,
perché voglio togliermi una \gbtooltip[right]{curiosità}{La curiosità consiste
nel sapere come si comporta il mio algoritmo in presenza di cose tipo
%\placeformula\startformula
%\sin^2 \alpha + \cos^2\alpha = 1,
%\stopformula
ovvero la cosiddetta {\en displayed math}}.
