ok thank you for the answers, but Gerald is right, and i belive he understands my problem, u have to open many files, i have to do a catalog that has 450 pages, split it in two it gets me 225 facing pages to open and change fonts, the ideea with the styles, i don't belive it would work because it's different styles in some pages, anf because the pages are not a like, they are different somehow. the thing, the font mapping, that quark has it it's simple but briliant, it seems that indesign is better that quark, but the lack of this rule really irritates me, and scripting is, for now, something strange to me.
