A Boolean question allows for a keyed response to indicate True or False. The entry of this question type is similar to keying a Single Categorical Response. A Boolean question cannot be entered with multiple responses; the response must be either True or False.

Enter the applicable keycode value in the Entry Panel, and then press.

The entered keycode value must match a valid value from the response list displayed for the current variable. For more information, see Resolving errors in keycode values.

When using a mouse, the only allows one response to be included in the Entry Panel. If you select a response, then select another response, only the most recently selected response appears in the Entry Panel (you cannot select multiple responses).
