Is there anything special about the "publicTemplates" key?

[curiosport]

I have a .toml file with multiple slices, similar to this:

publicTemplates = ["sample/files"]
chopicTemplates = ["sample/files"]
public = ["sample/files"]
templates = ["sample/files"]

When I run the following code:

v := viper.GetViper()
for _, key := range []string{
	"publicTemplates",
	"chopicTemplates",
	"public",
	"templates",
}{
	fmt.Println(fmt.Sprintf("Key: %s", key))
	fmt.Println(fmt.Sprintf("IsSet?: %v", v.IsSet(key)))
	fmt.Println(fmt.Sprintf("Value: %v", v.Get(key)))
}

I get this result:

Key: publicTemplates
IsSet?: false
Value: <nil>

Key: chopicTemplates
IsSet?: true
Value: [sample/files]

Key: public
IsSet?: true
Value: C:\Users\Public

Key: templates
IsSet?: false
Value: <nil>

For the public key I understand what it is because it is an environment variable in Windows, however I do not understand why, in the case of the publicTemplates and templates keys, Viper does not recognize them if they are declared in the configuration file and are not environment variables?
