When some windows appear, they force all mouse and keyboard control to the
window until the operator makes a selection from the window. This means that
the operator cannot respond to alarms that occur while this window is open.
The operator’s inability to respond to alarms could result in death or serious
injury to personnel and/or damage to equipment.
Make sure that the operator k nows that he must make a selection from the
window before responding to an alarm.
Cascaded Menus When menus appear, you choose a given item by
clicking on it. Some menu items have cascaded menus that appear when
you slide the cursor to follow the triangle indicator. When you cannot select
an item because of the current operation or display, the text of the item is
gray.

in OSx. Their action does not change from window to window.
OK Saves information that you have entered and closes the window.
