What does the object anchor symbol mean? How's it used?
An object may be in line with text, or it may have any one of a half-dozen
"floating" text-wrapping modes such as square or behind text.
When an object is floating, it is always associated with some specific paragraph
of text in the document. The object's anchor point is the upper left corner of
that paragraph. When you turn on the option to display the anchor symbol, it
appears in the left margin at the anchor point whenever the object itself is
selected.
The object may appear anywhere on the same page as the anchor point, but it
cannot be on another page. That means that if editing in the text moves the
anchor point to another page, the object will also move to the new page. Being
able to see the anchor symbol will help to explain why the object has moved.
When the anchor symbol is displayed, you can move the anchor point to a
different paragraph by dragging the symbol -- unless you open the object's
Format dialog, click the Advanced button on the Layout tab, and check the box
for "Lock anchor". Note that this does *not* lock the position of the object
with respect to the anchor point, nor does it prevent the object from moving to
a new page when the anchor point moves; it just prevents accidental dragging of
the anchor.
