Icon details	Target
Assuming that pages are created from other pages, then the creator page is the caller (parent) and the created page (child) is called the target. The creator page is always the link in the top left header box of a page. Similarly, if you link from one existing page to another existing page then the one you link from, is the caller, and the one you link to, is the target. This fits in well with the concept of firing one page from another, when the firing page is clearly the caller, and the fired page the target.
