I have a question about a formatting symbol
which looks like a small o, but appears to
float above the line. I found out it will keep
a phrase together, not allowing it to break to
another line. But my issues are:

1)What is this feature called, and is there a way
to turn it on and off?
2)a user is adding these unknowingly and it seems
to insert them randomly within the body of the
doc, and he does not want them or know why they are
being created.

I should also mention that the text is being created
within a table with cells, and don't know if that is
significant.

Could someone please resolve this mystery for me?
Much appreciated!!!!

Bill
