+    \qmlproperty bool QtQuick::EnterKey::type
+
+    This property holds the type of the Enter key.
+
+    \note Not all of these values are supported on all platforms.
+    For unsupported values the default key will be used instead.
+
+    \li Qt.EnterKeyDefault      The default Enter key.
+                                This can either be a button closing the keyboard, or a Return button
+                                causing a new line in case of a multi-line input field.
+    \li Qt.EnterKeyReturn       Show a Return button that inserts a new line.
+    \li Qt.EnterKeyDone         Show a "Done" button.
+                                Typically the keyboard is expected to close when the button is pressed.
+    \li Qt.EnterKeyGo           Show a "Go" button.
+                                Typically used in an address bar when entering a URL.
+    \li Qt.EnterKeySend         Show a "Send" button.
+    \li Qt.EnterKeySearch       Show a "Search" button.
+    \li Qt.EnterKeyNext         Show a "Next" button.
+                                Typically used in a form to allow navigating to the next input field
+                                without the keyboard closing.
+    \li Qt.EnterKeyPrevious     Show a "Previous" button.
