With the keys command you can either list all the locally available keys or show the address of a specific key. To list all the keys available run the following command:

jenesis keys list

To look up the address for a specified key you can use the show command and pass the key name as an argument:

jenesis keys show my_key
To access other key functionalities such as adding new keys, looking up an address, and recovering keys you can use fetchd CLI - Managing Keys
