The file menu contains command buttons that deal generally with input/output.
Pressing the Save button will pop-up a small dialog asking for a name for the file. This name can be anything, but it is recommended that a standard extension such as ``.sav'' be used to make these files easily recognized. Pressing the Save State button on the dialog will generate and save the state file.
Pressing the Recall button will pop up a small dialog asking for the name of the file. This can be entered directly, or the File Selection panel (from the File Select button) can be used to locate the file. Once located, the name of the file can be dragged from the File Selection panel and dropped in the dialog.
Pressing the Recall State button in the dialog will reconfigure the Merge Tool to the state found in the file. All entries in the tool should be as saved.
