There is a command set-theme. I can only find this below description in the WebIQ documenation. With 2 example theme names. From where do I get the complete list of the existing themes? And where they are defined?
set-theme
_Name of the theme (e.g. ‘xenon-acapulco-theme’, ‘xenon-emerald-theme’, etc.) If omitted the default theme is activated.
