Is there an action which opens the attachments panel? Not right away, but when the user presses some text?
I know the writer.setViewerPreferences(PdfWriter.PageModeUseAttachments) but I don't want it to open right away.

This can be done using a JavaScript action:
Chunk c = new Chunk("Show / Hide attachment panel"); c.setAction(PdfAction.javaScript( "app.execMenuItem('ShowHideFileAttachment');", writer)); document.add(new Paragraph(c));
Note that this won't work on all viewers (app = Adobe Reader) and it won't work if people disable Javascript.
