The default template file also contains an HtmlHead attribute with a long script text with many functions. This is actually a part of C1QueryFrame software, but it is written in JavaScript instead of C++ (which is the language of the rest of C1Query implementation). This is where all the functions are implemented, such as C1QShowCONNMenu, C1QInteractLS and others, mentioned in Tag substitution rules.
Advanced users can change the HtmlHead script just like any other template attribute customizing C1QueryFrame behavior event further. But beware, changing this script without due caution can break the C1QueryFrame control.
