 The `index` functions returns the result of indexing its first argument by the following arguments. Each indexed item must be a map or a slice, e.g.:
 
-```go-text-template
+```go-html-template
 {{ $slice := slice "a" "b" "c" }}
-{{ index $slice 1 }} => b
+{{ index $slice 0 }} → a
+{{ index $slice 1 }} → b
+
 {{ $map := dict "a" 100 "b" 200 }}
-{{ index $map "b" }} => 200
+{{ index $map "b" }} → 200
 ```
 
 The function takes multiple indices as arguments, and this can be used to get nested values, e.g.:
 
-```go-text-template
+```go-html-template
 {{ $map := dict "a" 100 "b" 200 "c" (slice 10 20 30) }}
-{{ index $map "c" 1 }} => 20
+{{ index $map "c" 1 }} → 20
 {{ $map := dict "a" 100 "b" 200 "c" (dict "d" 10 "e" 20) }}
-{{ index $map "c" "e" }} => 20
+{{ index $map "c" "e" }} → 20
 ```
 
 You may write multiple indices as a slice:
 
-```go-text-template
+```go-html-template
 {{ $map := dict "a" 100 "b" 200 "c" (dict "d" 10 "e" 20) }}
 {{ $slice := slice "c" "e" }}
-{{ index $map $slice }} => 20
+{{ index $map $slice }} → 20
 ```
 
 ## Example: load data from a path based on front matter parameters
 
 Assume you want to add a `location = ""` field to your front matter for every article written in `content/vacations/`. You want to use this field to populate information about the location at the bottom of the article in your `single.html` template. You also have a directory in `data/locations/` that looks like the following:
 
-```
-.
-└── data
-    └── locations
-        ├── abilene.toml
-        ├── chicago.toml
-        ├── oslo.toml
-        └── provo.toml
+```text
+data/
+  └── locations/
+      ├── abilene.toml
+      ├── chicago.toml
+      ├── oslo.toml
+      └── provo.toml
 ```
 
 Here is an example:
 
-{{< code-toggle file="data/locations/oslo" copy=false >}}
+{{< code-toggle file=data/locations/oslo >}}
 website = "https://www.oslo.kommune.no"
 pop_city = 658390
 pop_metro = 1717900
@@ -73,7 +68,7 @@ pop_metro = 1717900
 
 The example we will use will be an article on Oslo, whose front matter should be set to exactly the same name as the corresponding file name in `data/locations/`:
 
-{{< code-toggle file="content/articles/oslo.md" fm=true copy=false >}}
+{{< code-toggle file=content/articles/oslo.md fm=true >}}
 title = "My Norwegian Vacation"
 location = "oslo"
 {{< /code-toggle >}}
