7.3.6-2 Simple Input Actions for Selection

The user should be able to select a component or variable from a display by using simple input actions.

Additional Information:
Multi-step or complex input operations, such as transcribing identification codes, should be avoided. The demands of making a selection should be minimized so as not to compete with cognitive resources needed for assessing plant conditions and planning responses. However, in some cases, such as for controls that are very important to plant safety, more complex actions may be required to reduce the likelihood of accidental actuation.
