    13 query</title><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p>A confirmation query requests the user to confirm an operation, or asks

    15 a Yes-No-type of question. It can be used e.g. to make sure that the user

    16 does not accidentally delete important information or start an operation which

    17 cannot be cancelled.</p>

    18 <p>The layout for a Confirmation query is the same as the note layout, with

    19 an optional graphic item.</p>

    20 <p>One or two softkey labels can be used. In case the query can cause two

    21 different consequences, the positive choice (<b>Yes</b>) is placed on the

    22 left softkey, and the negative one (<b>No</b>) on the right softkey. In pure

    23 confirmations, only one way to proceed is possible, and the response text

    24 (for example <b>OK</b>) is placed on the left softkey.</p>

    25 <p>The Selection key always causes the same action as the left softkey.</p>

    30 <p>Guidelines for designing Confirmation queries:</p>

    31 <ul>

    32 <li><p>When designing the prompt text, make sure that the positive answer

    33 is also a safe one. Users tend to proceed pressing the left softkey or the

    34 Selection key without thinking too much. </p></li>

    35 <li><p>Redundant Confirmation queries should be avoided. Do not add a Confirmation

    36 query if there already are other forms of feedback, unless it is crucial that

    37 the user gets a certain piece of information.</p></li>

    38 </ul>
