Three groups of function keys are used in the CICS VR ISPF
dialog interface.
Standard function keys
Two standard function keys are available in all panels
and secondary windows.
Other function keys
These function keys are available in some CICS VR panels and secondary
windows in the ISPF dialog interface. They are available only in the panels
and secondary windows that contain objects to which they refer, so the function
performed by a key might change depending on the panel that is displayed.
Shortcut function keys
Some actions available on a menu have shortcut function keys. Pressing
the shortcut key causes the action, without selecting the action from the
menu.
