With Tibco's General Interface (GI) you can capture the fact that user has pressed the [Enter] key while the focus is within any textbox. By placing the javascript below in the Execute event for the textbox you can change the focus of the form when the user presses Enter.
jsx3.sleep(function() { ProjectNamespace.getJSXByName("[TextBoxNameHere]").focus(); });
replace 'ProjectNamespace' with the namespace in your project settings.
replace '[TextBoxNameHere]' with the name of the textbox that should receive focus next.
