Symbol
If the symbol and the symbol component are located in the same DGLux5 page, the path is the name of the symbol.
If the symbol is located in the project's palette folder, the path is palette/[folders, if any]/[page name]:[symbol name]. The page name does not use a .dg5 extension. For example, palette/widgets:sym is a valid path, where palette/widgets.dg5 is the file and sym is the symbol name.
If the symbol is located in a project in this project's lib folder, the path is lib/[project]/palette/[folders, if any]/[page name]:[symbol name]. For example, lib/HVAC2/palette/Equipment:Fan East is a valid path, where Equipment.dg5 is the file, and Fan East is the symbol name.
By default, this is the only property for a symbol. To create more properties for a particular symbol, open the Edit Properties dialog for that symbol.
