2.1-41 Indicating Appropriate Control Options

Users should be provided with a list of the control options that are specifically appropriate for any transaction.

Additional Information:
Transaction-specific options might be listed in the working display if there is space for them. Otherwise, they might be displayed in an overlay window at user request. Control options that are available for almost any transaction should be treated as implicit options, which need not be included in a list of transaction-specific options, unless they are particularly appropriate to the current transaction.
