Review for Book Text Mark by Paul Leger
Rated 5 out of 5 stars
Not to be mixed up with a text highlighter. This does not highlight text. It creates bookmarks as in a real, printed book to find a page or passage. So if you're working on veeeery long web pages, e.g. archived articles, digitalized books of a library, etc., then this is very useful to quickly scroll to specific lines or passages in the text.
