+      A command used to revoke a part of/the whole address public key, when the
+      user has access to a revocation certificate (but not the signing
+      capability of the key to use `key change`). A revocation certificate
+      must be attached to the message like a PGP key would. The revocation

+      a new one.
 
     `key sign`
+      A command used to add your signature to the list key, if you trust it. It
+      requires exactly one PGP public key attached, which should be the list
+      public key, signed with your address key. It is scanned for all new
+      certifications by your address key and the valid ones are imported. A
+      list might be configured to allow even a non-subscriber to sign its key.
