 A <<.def "filter operator">> is a predefined keyword attached to an individual [[step|Filter Step]] of a [[filter|Filters]]. It defines the particular action of that step.

+! Generating dynamic links
+
+[[Linking in WikiText]] does not lend itself well to creating dynamic links. The reason is because this WikiText link:
+
+```
+[[link to myself|Linking in WikiText]]
+```
+is shorthand for using the LinkWidget and TextWidget like this:
+
+```
+<$link to="Linking in WikiText">
+  <$text text="link to myself"/>
+</$link>
+```
+Since both the link title ("link to myself") and the link target ("Linking in ~WikiText") are used as widget attributes, no WikiText expansion takes place.
+
+For example, an attempt to use a [[reference|TextReference]] and a [[variable|Variables]] to dynamically generate a link like this:
+
+<<.bad-example "`[[{{!!caption}}|<<currentTiddler>>]]`">>
+
+is the same as trying to use the LinkWidget and TextWidget like this:
+
+<<.bad-example """```
+<$link to="<<currentTiddler>>">
+  <$text text="{{!!caption}}"/>
+</$link>
+```""">>
+
+This will not work as desired. Content inside of quoted widget attributes is [[treated as a literal value|HTML in WikiText]] and protected from WikiText expansion, so it will render like this:
+
+<<.bad-example "[[{{!!caption}}|<<currentTiddler>>]]">>
+
+In order to get the desired result, the LinkWidget can be used directly like this:
+
+<<wikitext-example-without-html src:"<$link to=<<currentTiddler>>>{{!!caption}}</$link>">>
