The keys function will return a list of all of the keys in one or more dict types. Since a dictionary is unordered, the keys will not be in a predictable order. They can be sorted with sortAlpha.

keys $myDict | sortAlpha

When supplying multiple dictionaries, the keys will be concatenated. Use the uniq function along with sortAlpha to get a unqiue, sorted list of keys.

``` keys $myDict $myOtherDict | uniq | sortAlpha
