Fledermaus Preferences
The tab bar across the top of the dialog shows the available preference groups. Selecting a tab will display its controls. There are also a number of buttons along the bottom of the dialog. The OK button applies all of the changed preferences and hides the dialog from view. The Cancel button dismisses the dialog without saving any changes. The Apply button sets all changed preferences without hiding the dialog box. The Reset button will reset the preferences to their default (starting) values.
