CSS Techs: 5.1 Specifying the direction of text

I'm having trouble understanding the technique-- the example isn't
clearly identified nor explained. Of course it could be that I just
don't know CSS all that well, but just in case...
 
<current>
Task:
 
Use 'direction' and 'unicode-bidi' to specify direction of text.
 
Text direction: 'direction', 'unicode-bidi'.
</current>
 
In other techniques, there is a heading that says "Example:" and it's
usually clearer how to apply the technique.
