Selective display is a method for telling Emacs to hide some text.
Another method is to use text properties, or overlays.

Outline mode is a major mode which can parse the text into a
hierarchical structure (the outline), and which provides commands for
hiding or showing certain parts of that hierarchical structure.
Outline mode also provides commands for navigating the structure.

When you tell outline mode to hide something, it could use selective
display to do that.  But I think that modern versions of outline mode
use text properties.  Selective display is a deprecated feature, I
think.

But don't take that too seriously -- maybe the term selective display
is wrong, and selective display is something else.

There is also the C-x $ command which can hide parts of the buffer
based on indentation.  It has selective display in its name.
