Currently only two of the submenus under the File menu are implemented; Exit, which simply exits the GRT shell, and Open Script. The Open Script option is for opening existing Lua scripts and is only implemented under Windows.

Sample scripts are found in the Scripts directory which is immediately below the installation directory. Opening a script from this menu option will create an additional tab labeled with the name of the script. Click on this tab to see the file contents. You may paste text between the GRT Shell tab and any script tab.

Under Linux the Shell menu shows menu items for closing the shell, refreshing the objects listed in the Global tree or saving the object tree.

The Save Tree ... menu option saves an XML file of all the data types and classes shown in the three tabs of the Objects Tree.

Under Linux there is no menu option to open a script.
