Defines the behavior of the ENTER key on an object. If this property is set to True, when users press the ENTER key that creates a new line on an object's text edition area. Otherwise, when users press the ENTER key focus goes to the next object in its tab order. This also occurs if the Multiline property is set to False, regardless of the value of this property.

The shortcut key CTRL + ENTER also depends on the value of the Multiline property. If this property is set to True, when those two keys are pressed that creates a new line on an object's text edition area, regardless of the value of this property. If this property is set to False, these keys have no effect on a text.
