Carriage Return in Gui question

Ah. I can't seem to lose focus on a GuiTextCntrl entry if I am editing that component. It seems that their is no global ActionMap definition for C/R processing so then processInputEvent() checks other consumers.
Not sure what I should be doing to finish and return to background screen. Do I need to pushDialog() something to finish the edit and lose the cursor always staying in the GuiTextEditCntrl field?
I have been looking at the code too long. ;)
