The tv-wikilinks variable controls the behaviour of the $link
widget.
The widget normally produces a link to a tiddler. But if this variable has the value no
, the widget suppresses the link and simply displays the text that would otherwise have served as the link.
You can suppress links for a whole tiddler by placing the following line at the start of the tiddler's text:
\define tv-wikilinks() no
This variable has no effect on external links, as those do not involve the $link
widget.
