Hello, I have a register where all the entries appear once (and only once) in a particular form (\index[def::]{entry}) but can appear any number of times in the standard form (\index{entry}). I would like the particular coupling to make all standard form entries clickable and linking to the one and only \index[def::]{entry}. This could be of course generalized to some kind of couplingcommand=\command#1#2 that is user-defineable ... -- Giuseppe "Oblomov" Bilotta
