In your text fields, configure an "On Enter Key Press Event". There, select a nanoflow, and in it make a javascript action that does the following:
const currentElement = document.activeElement;
if (currentElement) {
const tabEvent = new KeyboardEvent("keydown", {
key: "Tab",
bubbles: true,
cancelable: true,
});
currentElement.dispatchEvent(tabEvent);
}
There are fancier ways to do this, but this is probably the simplest - this one just simulates a tab press as soon as you press enter in a field.
