ReturnKey

Sent to the active object(glossary) when there is no text selection and the user presses the Return key.Syntax:

returnKey

Examples:

on returnKey -- go to the next card when the user presses return
  go next card
end returnKey

Handle the returnKey message when you want to perform an action when the user presses Return.

The Return key (confusingly labeled "Enter" on some keyboards) is usually located above the right-hand Shift key. It is the key you press to go to a new line.

The message is sent to the active (focused) control, or to the current card if no control is focused. If there is a text selection or insertion point in a field (or a button whose menuMode is "comboBox" ) and the user presses Return, the returnInField message is sent instead of returnKey.
