| 81 | To add a classifier, select it using the "Select classifier to add" pull-down list near the
|
|---|
| 82 | bottom and then click "Add Specified Classifier". A window appears entitled

| 83 | "Configuring Arguments"; instructions for this dialog are just the same as for
|
|---|
| 84 | plugins (see <a href="plugins.htm#plugins">Document Plugins</a>). Once you have configured the new
|
|---|
| 85 | classifier, it is added to the end of the "Currently Assigned Classifiers"

|

| 95 | The ordering of classifiers in the collection's navigation bar is reflected in

| 104 | The CustomAZList classifier is a special classifier that builds an alphabetical
|
|---|
| 105 | selection list ("AZList") and allows you to specify the letter ranges. This
|
|---|
| 106 | classifier has its own configuration dialogue. When a metadata element is
|
|---|
| 107 | selected, the "Ranges" tree automatically becomes populated with appropriate
|
|---|
| 108 | values. Expand or collapse the tree as desired. Select any two values and
|
|---|
| 109 | click "Merge" to specify a range, or select a previously merged value and click
|
|---|
| 110 | "Split" to restore the values contained within. When satisfied with the ranges,
|
|---|
| 111 | click "OK" to begin processing the documents in the collection. You can
|
|---|
| 112 | "Cancel" the dialog without making any changes to the collection.
