2.5.2-12 Consistent Window Control

User control of windows should operate consistently from one display to another for each type of window.

Additional Information:
Control of predefined windows may simply involve "opening" and "closing" them, by selection of displayed option labels or function keys. Control of user-defined windows may require user specification of window contents, window size, and positioning on the display. Such window control must be learned by a user, and consistent design of control logic aids that learning.
