Bookmarks
InformationsAuthor: Olivier
License: Freeware
DescriptionThis extension adds bookmark support. The method to add a bookmark is:
function Bookmark(string txt [, int level [, float y]])
txt: the bookmark title.
level: the bookmark level (0 is top level, 1 is just below, and so on).
y: the y position of the bookmark destination in the current page. -1 means the current position. Default value: 0.
