How to use hashtags in Facebook ?

Hashtags can transform discussion topics and phrases into links "clickable" in publications on your personal journal or Page. They make it easier to find publications on specific topics. To use a hashtag, enter # (touch dièse) followed by a discussion topic or written as one word phrase, then add them to your publication (example : She is beautiful, the City of Light ! #Paris).

When people click on a hashtag, a wire composed of publications that have been shared with them and use the same hashtag appears.
