The Delete command removes the current selection from the sound file, without modifying the contents of the clipboard. Use Delete instead of Cut when something is on the clipboard that should not be overwritten or when you are sure you do not want to use the selection again.
Click MENU on Delete to display the Delete submenu with the following options:
Selection--This is the default,
which deletes the current audio selection.
option deletes everything that is not selected. This
enables you to select the part of an audio segment that you want, then delete
the parts that you don't want.
option deletes all silent segments, which are indicated by horizontal lines.
This is useful, for example, when you are sending or storing voice mail.
option deletes only the silent segments at the beginning and end of the file.
This enables you to remove a pause that occurs between the time you press
the Rec button and start talking, or the pause between the time that you stop
talking and press the Stop button.
