Once you have made any necessary backups of your Destination File sounds, previewed your Destination and Source Files, and decided which sounds you want to change, you are now ready to begin customizing.
Replacement is rather  
straight-forward. Simply select the
sound in the Destination File List
you wish to replace by clicking on
it, then select the sound you wish
to replace it with from the Source
File List. Then, click on the
"Replace/Copy Sound" button
located in the middle of the two lists.
Upon doing so, the selected sound
in the Destination File List is instantly
replaced by the selected sound from
the Source File List. The newly re-
placed sound in the Destination File
List is now marked as "changed" by a
black bullet to the left of the resource
name, as shown to the right.
Replacement can also be done by simply dragging the selected sound in the Source Files List to the selected sound in the Destination File List. This will perform the same function as clicking the "Replace/Copy Sound button," and will also cause the replace sound to be marked with a bullet to the left of the resource name.
  Another method of replace-
ment is to select "Replace
Selected Sounds" from the
Edit menu on the menu bar.
The keyboard command for
replacing is Command-M.
The "Pro" version of Agent Audio allows you to select and replace multiple sounds at one time, as well as add sounds to software. For more information, see the "Agent Audio Pro CD-ROM" section.
Reverting To Last Saved
 You can revert to the last saved state of your Destination File at
any time once changes are made in your Destination File. There
are three ways to revert, the first of which is to click the "Revert"
button located at the bottom-left corner of the Destination File List.
 
You can also select "Revert Destination
File" from the File menu on the menu
bar, or use the keyboard command,
which is Command-B.
Saving Changes
 Once you have customized your Destination File, you are
ready to save the changes. There are three ways to do this,
the easiest of which is to click the "Save" button located at
far left of the button bar at the bottom of the Agent Audio Pro
window. 
You can also select "Save Destination
File" from the File menu on the menu bar
or use its keyboard equivalent of Com-
mand-S. Upon saving changes, the
bullets that once marked the changed
sounds disappear.
 If you are finished customizing the Destination File, you can close it by
clicking on the "Close Destination File" button located at the bottom of
