Usually, tags modify the appearance of text in the view, e.g. making it
bold or colored or underlined. But tags are not restricted to appearance.
They can also affect the behavior of mouse and key presses, as this demo
shows.Nt

appearance of a hyperlink in a web browser: blue and underlined.
Additionally, attaches some data on the tag, to make it recognizable
as a link.

d n d S( s Fills the buffer with text and interspersed links. In any real
hypertext app, this method would parse a file to identify the links.
t i i s Some text to show that simple t hypertexti s can easily be realized with RA i t .sw A tag is an attribute that can be applied to some range of text. For example, a tag might be called "bold" and make the text inside the tag bold. However, the tag concept is more general than that tags don't have to affect appearance. They can instead affect the behavior of mouse and key presses, "lock" a range of text so the user can't edit it, or countless other things.

sr machine-readable text that is not sequential but is organized so that related items of information are connected.
