$context['meta_keywords']

[Sincere]

hello.
themes/default/index.template.php

<meta name="keywords" content="', $context['meta_keywords'], '" />

Where in the admin panel do you control the meta keywords ?

Admin area > Features and Options > Layout

Admin area > Features and Options > Layout

thank you very much. I really appreciate your help.

I thought Layout means "design", that is, how the forums are laid .......  I did not expect that the keywords might be under "layout"

hmm I agree it isn't too logical. I can only assume it is there because it has a link to the theme headers.
