+Code blocks can include a button to allow for the selection of line ranges by
+the user, which is perfect for linking to a specific subsection of a code block. This allows the user to apply [line highlighting] dynamically. Add the following
+to `mkdocs.yml` to enable it globally:

+  features:
+    - content.code.select
+```
+
+??? info "Enabling or disabling code selection buttons for a specific code block"
+
+    If you don't want to enable code selection buttons globally, you can enable 
+    them for a specific code block by using a slightly different syntax based on 
+    the [Attribute Lists] extension:
+
+    ```` yaml
+    ``` { .yaml .select }
+    # Code block content
+    ```
+    ````
+
+    Note that the language shortcode which has to come first must now also be 
+    prefixed by a `.`. Similarly, the selection button can also be disabled for
+    a specific code block:
+
+    ```` { .yaml .no-select }
+    ``` { .yaml .no-select }
+    # Code block content

-In order to be able to link to code annotations and share them more easily, an
-anchor link is automatically added to each annotation, which you can copy via
-right click or open in a new tab:
+Normally, code annotations can only be [placed in comments], as comments can be
+considered safe for placement. However, sometimes it might be necessary to place
+annotations in parts of the code block where comments are not allowed, e.g. in 
+strings.
+
+Additional selectors can be set per-language:
 
 ``` yaml
-# (1)!
+extra:
+  annotate:
+    json: [.s2] # (1)!
+```
+
+1.  [`.s2`][s2] is the name of the lexeme that [Pygments] generates for double-quoted
+    strings. If you want to use a code annotation in another lexeme than a
+    comment, inspect the code block and determine which lexeme needs to be added
+    to the list of additional selectors.
+
+    __Important__: Code annotations cannot be split between lexemes.
+
+Now, code annotations can be used from within strings in JSON:
+
+``` json
+{
+  "key": "value (1)"
+}
 ```
