 There are a few special data keys you can assign in your data to control how templates behave. These can live anywhere in the [Data Cascade](/docs/data-cascade/).
 
 * `permalink`: Change the output target of the current template. Normally, you cannot use template syntax to reference other variables in your data, but `permalink` is an exception. [Read more about Permalinks](/docs/permalinks/).
-	* `dynamicPermalink`: Option to disable template syntax for the `permalink` key. [Read more](/docs/permalinks/#disable-templating-in-permalinks).
-  * `permalinkBypassOutputDir`: Write a file to somewhere other than the output directory. [Read more](/docs/permalinks/#ignore-the-output-directory)
 * `layout`: Wrap current template with a layout template found in the `_includes` folder. [Read more about Layouts](/docs/layouts/).
 * `pagination`: Enable to iterate over data. Output multiple HTML files from a single template. [Read more about Pagination](/docs/pagination/).
 * `tags`: A single string or array that identifies that a piece of content is part of a collection. Collections can be reused in any other template. [Read more about Collections](/docs/collections/).
 * `date`: Override the default date (file creation) to customize how the file is sorted in a collection. [Read more at Content Dates](/docs/dates/).
 * `templateEngineOverride`: Override the template engine on a per-file basis. [Read more about Changing a Template’s Rendering Engine](/docs/languages/#overriding-the-template-language). [_This option only works in Front Matter ⚠️ (for now), read Issue #445_](https://github.com/11ty/eleventy/issues/445).
