The content of the link widget is rendered within the `<a>` tag.
The default value of the tooltip attribute is `<<tv-wikilink-tooltip>>`.

! Configuration macros
! Configuration variables
Configuration macros can be used to modify the behaviour of the link widget.
!! tv-wikilinks
Links are suppressed if the macro `tv-wikilinks` evaluates to the string `no`. For example:
```
\define tv-wikilinks() no
```
!! tv-wikilink-template
The target of the link widget defaults to the URL encoded title of the tiddler. The `href` can be templated by defining the configuration macro `tv-wikilink-template`, and including within it the token `$uri_encoded$`. For example:
```
\define tv-wikilink-template() http://tiddlywiki.com/#$uri_encoded$
```
The token `$uri_doubleencoded$` is replaced by the double encoded title of the tiddler.
Note that in the browser the `<a>` element generated by the link widget has a JavaScript event handler that navigates directly to the target tiddler, ignoring the `href` attribute.
!! tv-wikilink-tooltip
Provides default text for the link tooltip:
```
\define tv-wikilink-tooltip() This is a link to {{!!title}}
<$link to="HelloThere"/>
```
