This HTML template is only used for Webhelp. It generates the keyword index pane within the frame layout that emulates the appearance and functionality of the HTML Help viewer in a normal browser.
The keyword index template is an integral part of the help viewer generated by Help & Manual for Webhelp. Its code is essential for the proper functioning of the index. Please be extremely careful when you are editing this template – if you don't understand what a piece of code is for it's better to leave it alone!
When you publish the actual keyword index is inserted in the Index page by the <%KEYWORD_INDEX%> variable.
See Editing HTML templates for details on how to edit templates.
