Choices for showing PF keys on the display screen

By selecting "Show all function keys", "Show partial function keys", or "Remove function key display", you can specify that ISPF use the long form of function key display, the short form of function key display, or no function keys, respectively.

Each of these pull-down choices has an equivalent PFSHOW and FKA command associated with it. The commands operate as toggles; the pull-down choices become unavailable if they are the current setting.

This table explains the relationship between the pull-down choices and their related command combinations.

Table 1. Displaying forms of the function keys
Pull-down Choice	Command Equivalent	Result
Show all function keys	PFSHOW PFSHOW ON FKA FKA ON	Long setting; all available function keys displayed. This is the default setting.
Show partial function keys	PFSHOW (second time issued) FKA (second time issued) FKA SHORT*	Short setting; a partial listing of the function keys displayed.
Remove function key display	PFSHOW (third time issued) PFSHOW OFF FKA (third time issued) FKA OFF	No function keys displayed. If PFSHOW or FKA is issued for a fourth time, the display returns to the long, or ON, setting.
Note: * The FKA SHORT command can be issued at any time to invoke the short setting.
