Exploring global variables¶

Many of the global variables described above can be inspected using the module System > Configuration.

Warning

This module is always viewed in the BE context. Variables defined only in the FE context will not be visible there.

Note

This module is purely a browser. It does not let you change values.

It also lets you browse a number of other global arrays as well as values defined in other syntaxes including YAML.
