Help menu > Additional Help
Click Additional Help to display help files for installed third-party plug-ins, and for add-on products from Discreet.
This command is set by default to look for third-party help files installed to \help subdirectory, though that location may have changed if you've edited plug-in path settings. Plug-in path information is stored in the plugin.ini file.
To view help for the plug-ins:
Choose Help > Additional Help.
Choose the plug-in for which you want help.
Click Display Help.
