In navigational hypertexts, following a link replaces the page with a new page.

In stretchtext, following a link expands a passage or collapses an expanded passage. Stretchtext retains the interactivity of hypertext, but limits the disruption that accompanies link traversal.

Peter J. Brown's GUIDE (Office Workstations Ltd. 1987), one of the first commercial hypertext tools, employed stretchtext.
