Why does it matter whether the submenu is showing?

[Deepak, 2014/08/20 03:37:33]

As When Submneu is shown, and we select F4, we wanted to dismiss submenu and
don't want to show the selection in the submenu.

and if submenu is not shown and we select F4 then we want submenu to be shown,
To get the same windows behavior.
