Language selection (WPML-based) in Header

Hi there

I successfully activated the WPML template and it works smoothly with my Aqua theme. However now I would like to implement a language switcher in the top right corner of the page (above the search field).

The question is now which code to use and where to place it in order to make this work?

1. WPML offers a standard module (Flag + Language Name) which can be entered via the following code:

< ?php do_action('icl_language_selector'); ?>

Will this work with Aqua and where do I have to insert this code?

2. Is there any other option to use a simple text link? E.g. the “traditional” EN | DE | FR or German | English | French?

Thanks for your help
