Creating custom links

In a Joe Workman stack you have the option to link. You choose the page to link to and you can add custom targets.
Is there a list of the allowed things to put in there?
I simply want a link to jump to a set place on my page which I think is normally achieved by adding #placeholder if the place you want to jump to is called placeholder, for instance.
Stack used is Total CMS blog post and the target is a Sections Pro link for MagicGellan
