You can edit the attribute definitions in blocks, remove attributes from blocks,
and change the order in which you are prompted for attribute values when inserting
a block.

Attributes of the selected block are displayed in the attribute list. By default,
Tag, Prompt, Default, Mode, and Annotative attribute properties are displayed in the
attribute list. For each selected block, a description below the attribute list identifies
the number of its instances in the current drawing and in the current layout.

You can specify which attribute properties you want displayed in the list by choosing
Settings.

Double-click an attribute to display the Edit Attribute dialog box, where you can
modify attribute properties.

If you modify attributes of a block and then select a new block before you save the
attribute changes you made, you are prompted to save the changes before selecting
