Как сделать что бы при нажатие стрелочки вверх появлялся блок?

Я имею такой код.
<div class="map">
    <div class="airplane"></div>
    <div class="point point_1"></div>
    <div class="point point_2"></div>
    <div class="point point_3"></div>
    <div class="point point_4"></div>
    <div class="point point_5"></div>
    <div class="point point_6"></div>
</div>

Это аэроплан, мне нужно что бы он появлялся только при нажатии стрелочки вверх на клавиатуре. (Типо пасхалки) Но так как я новичок я не знаю как это сделать. Заранее спасибо

@Aricus
Через javascript это нужно делать. Добавьте к аэроплану CSS-класс с display:none, а в javascript при событии onkeypress и условии e.key == 'ArrowUp' удалите этот класс.
