A veces puede ser difícil conseguir que el cajón de marcadores llegue a su punto máximo de forma fiable en dispositivos con bordes curvos,
por lo que también es posible abrir el cajón de marcadores desde el menú de opciones.</p>
- <p>Tapping on a bookmark opens it in the current tab. Long-pressing on a bookmark opens it in a new tab and long-pressing on a folder opens all the bookmarks it directly contains in new tabs.
+ <p>Al pulsar sobre un marcador, lo abre en la pestaña actual.
+ Una pulsación larga sobre un marcador lo abre en una nueva pestaña y una pulsación larga sobre una carpeta abre todos los marcadores que contiene directamente en nuevas pestañas.
Al tocar el botón de acción superior flotante en el cajón de marcadores se abre la actividad de marcadores, donde se pueden editar y reorganizar los marcadores.</p>

Il est parfois difficile de faire apparaître le gestionnaire de favoris de manière fiable sur les appareils aux bords incurvés,
c'est pourquoi il est également possible d'ouvrir le gestionnaire de favoris à partir du menu des options.</p>
- <p>Tapping on a bookmark opens it in the current tab. Long-pressing on a bookmark opens it in a new tab and long-pressing on a folder opens all the bookmarks it directly contains in new tabs.
+ <p>Un appui sur un favori l'ouvre dans l'onglet actuel.
+ Un appui long sur un signet l'ouvre dans un nouvel onglet et un appui long sur un dossier ouvre tous les signets qu'il contient directement dans de nouveaux onglets.
Si vous appuyez sur le bouton d'action flottant supérieur dans le gestionnaire de favoris, vous ouvrez un volet dans lequel vous pouvez modifier et réorganiser les favoris.</p>

панель можно открыть длительным нажатием на край экрана <a href="https://redmine.stoutner.com/boards/1/topics/243">до ее появления</a>, а затем смахнув.
На устройствах с изогнутыми краями иногда бывает непросто добиться появления панели закладок, поэтому можно открыть ее из меню параметров.</p>
- <p>Tapping on a bookmark opens it in the current tab. Long-pressing on a bookmark opens it in a new tab and long-pressing on a folder opens all the bookmarks it directly contains in new tabs.
+ <p>При нажатии на закладку она откроется на текущей вкладке.
+ При длительном нажатии на закладку она откроется на новой вкладке, а при длительном нажатии на папку все закладки, которые она содержит, откроются в новых вкладках.
При нажатии верхней кнопки действия в панели закладок открывается страница действий с закладками, где их можно редактировать и упорядочивать.</p>
