The Script Management dialog shows you all your installed script add-ins. You can create new scripts or manage your existing ones from here.
To get to the Script Management dialog, use the Scripts command in the default Settings menu. If you're using old toolbars without that command in them, you can add it from the Customize / Default Toolbars tab. The raw command is Prefs SCRIPTS.
Your installed scripts are shown in the list, with a number of columns:
If a script has configuration options, it will be indicated with a cog icon - you can click this icon or use the Configure button in the toolbar to edit the configuration.
Scripts can specify a group as part of their initialisation - if any scripts have done this, the script list will be split into two or more groups.
By default include file scripts are also shown in the list, but you can hide them with the command in the File menu.
The easiest way to install a new script is with the File > Install command (or click the Install button on the toolbar).
The script installer will open to guide you through the install process. You can install single script files (e.g. .js or .js.txt), script packages (.osp files) and script install files (.opusscriptinstall files) this way.
Click the New button to create a new script. The Create New Script dialog opens.
Select a script from the list to see information about it at the bottom of the dialog.
You can right-click a script, or use the Script drop-down menu, to manage the selected script. Some of these functions are also available on the toolbar itself.
