Can I use pdfdde to send Control-LeftArrow to the Acrobat Reader? If yes, how? pdfclose and pdfopen are already very helpful before and after running pdf(la)tex. Hitting Control-LeftArrow then brings me back to the page in the document I was before. Is there any documentation on (pdfopen, pdfclose,) pdfdde? Who wrote the programs? Fabrice Popineau? Best regards and thanks in advance, Peter Harmand
