+-complete @var{command}

+
+Show a list of completions for partially typed CLI @var{command}.
+
+This command is intended for @sc{gdb/mi} frontends that cannot use two separate
+CLI and MI channels - for example: because of lack of PTYs like on Windows or
+because @sc{gdb} is used remotely via a SSH connection.
