The links or anchor if text will show up styled as a link defined by the theme your using.
f you are trying to link to another to another spot on the same page (the anchor point) would have to have a unique name. if you are selecting text as an anchor point then it will look link it is an outbound link. A number of themes underline or highlight external text links, so its best to use somthing else as an anchor point like an image.
joeworkmans free stack:
http://joeworkman.net/rapidweaver/stacks/link-anchor/
does work for both, the doc and video are more talking about the link side so I think people get confused.
Put the anchor stack here you want to go, give it a unique name.
The link stack can be used to create a link for stacks that don’t have a link bult in just put it on the page and add the stack.
so to setup an anchor with @joeworkman 's stack place the anchor stack were you want to scroll to, give it a unque name(if you using multiple anchors on same page):
(example using moreinfo)
(This is what the stack will look like in edit mode)
On the link side (were you are linking from) set the link to a URL with just the #info (no href)
This will work for samepage navigation.
@zeebe has a couple of great post on navigating to an anchor on other pages.
