 ### Keywords
 
 You can use shorthand for some types of interfaces:
 
-* `error` for `error` type
 * `empty` for `interface{}` type
 * `anon` for anonymous declarations `interface{ someMethod() }`
-* `std` for all interfaces from standard library.
+* `error` for `error` type
+* `stdlib` for all interfaces from standard library.
+* `generic` for generic interfaces (added in go1.18)
