+The @code{gpgme_edit_cb_t} type is the type of functions which
+@acronym{GPGME} calls if it a key edit operation is on-going.  The
+status code @var{status} and the argument line @var{args} are passed
+through by @acronym{GPGME} from the crypto engine.  The file
+descriptor @var{fd} is -1 for normal status messages.  If @var{status}
+indicates a command rather than a status message, the response to the
+command should be written to @var{fd}.  The @var{handle} is provided
+by the user at start of operation.
+
+The function should return @code{GPG_ERR_NO_ERROR} or an error value.

+The function @code{gpgme_op_edit} processes the key @var{KEY}
+interactively, using the edit callback function @var{FNC} with the
+handle @var{HANDLE}.  The callback is invoked for every status and
+command request from the crypto engine.  The output of the crypto
+engine is written to the data object @var{out}.
+
+Note that the protocol between the callback function and the crypto
+engine is specific to the crypto engine and no further support in
+implementing this protocol correctly is provided by @acronym{GPGME}.
+
+The function returns the error code @code{GPG_ERR_NO_ERROR} if the
+edit operation completes successfully, @code{GPG_ERR_INV_VALUE} if
+@var{ctx} or @var{key} is not a valid pointer, and any error returned
+by the crypto engine or the edit callback handler.

+The function @code{gpgme_op_edit_start} initiates a
+@code{gpgme_op_edit} operation.  It can be completed by calling
+@code{gpgme_wait} on the context.  @xref{Waiting For Completion}.
+
+The function returns the error code @code{GPG_ERR_NO_ERROR} if the
