Function keys

ISPF uses CUA-compliant definitions for function keys F1-F12 (except inside the Edit function). F13-F24 are the same as in ISPF Version 3. By default you see the CUA definitions because your "Primary range" field is set to 1 (Lower - 1 to 12).

To use non-CUA-compliant keys, select the "Tailor function key display" choice from the Function keys pull-down on the ISPF Settings (option 0) panel action bar. On the Tailor Function Key Definition Display panel, specify 2 (Upper - 13 to 24) in the "Primary range" field.

These function keys help you navigate in ISPF:

F1: Help. Displays Help information. If you press F1 (and it is set to Help) after ISPF displays a short message, a long message displays in a pop-up window.
F2: Split. Divides the screen into two logical screens separated by a horizontal line or changes the location of the horizontal line.
Note: If you are running in GUI mode, each logical screen is displayed in a separate window.
F3: Exit (from a pull-down). Exits the panel underneath a pull-down.
F3: End. Ends the current function.
F7: Backward. Moves the screen up the scroll amount.
F8: Forward. Moves the screen down the scroll amount.
F9: Swap. Moves the cursor to where it was previously positioned on the other logical screen of a split-screen pair.
F10: Actions. Moves the cursor to the action bar. If you press F10 a second time, the cursor moves to the command line.
F12: Cancel. Issues the Cancel command. Use this command to remove a pull-down menu if you do not want to make a selection. F12 also moves the cursor from the action bar to the Option ==> field on the ISPF Primary Option Menu. See z/OS ISPF Dialog Developer's Guide and Reference for cursor-positioning rules.
F16: Return. Returns you to the ISPF Primary Option Menu or to the display from which you entered a nested dialog. RETURN is an ISPF system command.
