This free FKEY makes it easy to see a list of all installed FKEYs.
Calling the FKEY “freezes” the current screen and displays a window with all FKEYS listed by name and command key, even those outside of the normal ID range of 0 to 9.
This FKEY ID is 0. It can be installed with Suitcase or copied into the System File using ResEdit, renumbering as necessary.
