For an ISPF session

You can use the standard ISPF capability of assigning functions to PF keys by calling the ISPF command KEYS. Most PF keys in Monitor II have the standard setting as in all other ISPF applications. There are two exceptions:

PF5

RFIND command

PF6

SORT command

If you want to make your own settings, you might use PF10 and PF11 (or PF13 — PF24), they have no predefined meaning in an ISPF Monitor II session. All PF key definitions remain valid across sessions.
