How does the tag feature work?

Hi,
I trying to use tag words when i create a new item but it just wont tag in...

may i know how it works?

If you type the first letters of the tag, then a list of existing tags that start with these letters appear, you can now click in the list, to add the tag you want.

If you want to create a new tag, then you write the new tag and click enter, the new tag is then created and at same time added to the current item.

To see all available tags go to the tags manager, there you can also add and delete tags, you can also see how many items are using a tag.

I have noticed that a link to display the items using a tag is missing ... will add in v1.5.7

Regards
