Aside from the separately discussed "Add" and "Edit" buttons there are few more buttons:
Remove
This button is only visible and accessible in combination with custom scripts, plugins, and graphs; built-in commands are not affected.
Export
With this button you can write out an XML file containing all commands. This is very useful for creating and synchronizing different RealFlow installations, or changing the layout of an external RealFlow copy to your needs when you work as a freelancer. In the latter case you just copy all shelves, shortcut, and layout files to an USB stick, and import these definitions to your new workplace.
