Editing a character set involves adding or removing attributes from the set. By default, a character set includes all the keyable attributes of the objects included in the character. Typically, you only want to work with some of these attributes. Depending on the number and complexity of the objects included in the character, keeping all of these attributes in the character set can result in a needlessly long list of channels in the Channel Box. Consequently, after you create a character set, you may find you want to remove some of the attributes from the character set. Of course, you can later add them back to the character set.
