+# Configure default view
+
+The default view in Zulip is the view you reach after logging in
+to the Zulip web app. You can also navigate to the default view via
+keyboard shortcuts.
+
+The default views available in Zulip are
+[Recent topics](/help/recent-topics) and
+[All messages](/help/reading-strategies#all-messages). See
+[Reading strategies](/help/reading-strategies) for recommendations
+on how to use these views.
+
+You can configure which view is set as your default, and whether
+the `Esc` key navigates to the default view. Also, you can always reach
+the default view by using the `Ctrl + [` shortcut.
+
+## Change default view
+
+Organization administrators can [set the default view for their
+organization](/help/configure-default-new-user-settings) to
+[**Recent topics**](/help/recent-topics) or
+[**All messages**](/help/reading-strategies#all-messages).
+**Recent topics** is especially recommended for high-traffic
+organizations, and is configured by default.
+
+You can customize your personal default view regardless of
+organization settings:
+
+{start_tabs}
+
+{settings_tab|display-settings}
+
+2. Under **Advanced**, click on the **Default view** dropdown
+and select a view.
+
+1. To see your changes in action, open a new Zulip tab, or use a keyboard
+shortcut twice to exit the settings and navigate to your default view
+(`Ctrl + [` or `Esc` if enabled).

+
+## Set whether `Esc` navigates to the default view
+
+Zulip has a number of [keyboard shortcuts](/help/keyboard-shortcuts)
+designed to enhance the user experience in the app.
+
+By default, the `Esc` key shortcut will ultimately navigate to your
+default view. You can disable this keybinding if you would prefer.
+This will not disable other `Esc` key shortcuts used in Zulip,
+and will not affect the behavior of the `Ctrl+[` shortcut.
+
+### Toggle whether `Esc` navigates to the default view

+
+{settings_tab|display-settings}
