للتنقّل بين العلامات باستخدام لوحة المفاتيح، اتّبِع الخطوات التالية:
استخدِم مفتاح التبويب للتركيز على العلامة الأولى، وإذا كانت هناك علامات متعددة على الخريطة نفسها، استخدِم مفاتيح الأسهم للتنقّل بين العلامات.
إذا كان العلامة قابلة للنقر، اضغط على مفتاح Enter "للنقر". إذا كان هناك نافذة معلومات مرتبطة بعلامة، يمكنك فتحها من خلال النقر عليها أو الضغط على مفتاح Enter أو مفتاح المسافة. عند إغلاق نافذة المعلومات، سيعود التركيز إلى العلامة المرتبطة بها.
اضغط على مفتاح التبويب مرة أخرى لمواصلة التنقّل بين بقية عناصر التحكّم في الخريطة.
لتحسين إمكانية الوصول إلى المحتوى، يُرجى اتّباع الخطوات التالية:
اضبط نصًا وصفيًا لعلامة باستخدام الخيار Marker3DInteractiveElement.title.
أضِف محتوى إلى الخانة header في PopoverElement.
يمكنك تكبير حجم العلامة باستخدام السمة PinElement.scale.

Default markers meet the [WCAG AA minimum\n size](https://www.w3.org/WAI/WCAG22/Understanding/target-size-minimum.html) standard but for developers aiming to comply with the [WCAG AAA\n target](https://www.w3.org/WAI/WCAG21/Understanding/target-size.html) size standard the marker size should be increased.\n\nSee [basic marker\ncustomization](/maps/documentation/javascript/3d/marker-customization) to learn\nhow to change marker scale, add title text, and more.\n\nThe following example shows a map with five clickable, focusable markers that\ninclude title text, and have been set to 1.5x scale:\n\n\nJavaScript \n\n```javascript\nasync function initMap() {\n const { Map3DElement, Marker3DInteractiveElement, PopoverElement } = await google.maps.importLibrary(\"maps3d\");\n const { PinElement } = await google.maps.importLibrary(\"marker\");\n const map = new Map3DElement({\n center: { lat: 34.8405, lng: -111.7909, altitude: 1322.70 }, range: 13279.50, tilt: 67.44, heading: 0.01,\n mode: 'SATELLITE'\n });\n // Set LatLng and title text for the markers.

When the info window closes, focus will return to the associated marker.\n3. Press tab again to continue moving through the rest of the map controls.\n\nTo enhance accessibility:\n\n- Set descriptive text for a marker using `Marker3DInteractiveElement.title` option.\n- Add content to the `header` slot of `PopoverElement`.\n- Increase marker scale using the `PinElement.scale` property."]]
