Common Screen Elements
purpose of the screen you are viewing. Some of the more common
function keys are described here. For many screens, you can find
information on that screen’s function keys in the Help information
associated with the screen.
Prior Screen Key
Except for a limited number of screens, such as the Error Information
screen and the Guided Configuration screen, the
[Prior Screen] key is
the right-most function key,
[f8].
With a few exceptions (as listed), the screen displayed when
[Prior Screen] is pressed will always be the screen most recently visited
prior to the current screen, regardless of the manner in which you
reached the current screen. In order to show the correct screen,
NMMGR maintains a prior screen list, which is a sequential list of
the screens that have been displayed. Pressing
[Prior Screen] displays
the most recent screen in the prior screen list and removes that screen
from the list.
The most recent screen in the list is the screen that was visited just
prior to the current screen, with five exceptions:
• When you display the Error Information screen, NMMGR does not
put this screen in your prior screen list. Thus, pressing
[Prior Screen]
never transfers you to the Error Information screen, even if it was
the latest screen you displayed.
• After reaching the Validate screen in guided configuration, the prior
screen becomes the screen with which you began the guided
configuration.
• If you use the command window to return to a screen already visited,
NMMGR drops any screens visited after this screen from the prior
screen list.
• If you use the
[Help] key to display a help information screen, the
help screen will not appear in the prior screen list.
• Using the NEXT command does not update the prior screen list.
Help Key
Most NMMGR screens have a [Help] key as the second key from the
right. Pressing this key displays a help information screen. The help
information relates specifically to the screen from which you pressed
the
[Help] key. It describes screen usage, parameters, and function key
operation for that screen. See “Getting Help” in this chapter for more
information on the NMMGR Help system.
