+## Pick keys from map, included all the keys
+We create a map of the picked keys plus all the current keys, and run that through unique
+
+Given a sample.yml file of:
+```yaml
+myMap:
+  cat: meow
+  dog: bark
+  thing: hamster
+  hamster: squeak
+```
+then
+```bash
+yq '.myMap |= pick( (["thing"] + keys) | unique)' sample.yml
+```
+will output
+```yaml
+myMap:
+  thing: hamster
+  cat: meow
+  dog: bark
+  hamster: squeak
+```

 ## Pick indices from array
 Note that the order of the indices matches the pick order and non existent indices are skipped.
