Front

how you type the path?
it should be relative path like node for front page if you set in site information front page as node.

Hi,
I understand how to set the theme for the front page by setting that theme for the node that is used for the front page. However I would like to be able to use a different theme depending on whether that node has been accessed by a) clicking on the site title or going to the root path (with no q= argument) or b) accessing the node itself, either through the node/# path, an alias path, or through the primary links menu (which obviously uses one of two other paths). So basically if the user has the impression that they are navigating to the root of the site they see one theme; if they have the impression that they are navigating within the site, they see another.
This strikes me as sort of tricky but could maybe be done if the referring page property was exposed to ThemeKey?

Use property drupal:is_front_page provided by module ThemeKey Properties.
