This option sets the default "target" window to point links created with the Link dialog window. It may be set to any of the "reserved" target names (_blank, _self, _parent or _top) or even to a custom name. Example:
FCKConfig.DefaultLinkTarget = '_self' ;
If left empty, no target is set by default.
NOTE: Users will still be able to change the target using the "Target" tab in the link dialog window. To force links to be created with the configured target, just hide that "Target" tab by using the LinkDlgHideTarget setting.
