Press F key twice to arm to Vacation mode ?

[timop001]

I have a response attached to the F key to arm to vacation mode i.e. press F twice.I noted recently this no longer works but can\'t understand why. The response is still there (and works if executed from Comfigurator) and is attached to the F key but pressing it twice gives a long bleep error tone.
I have put the new 9001 board in and changed one of the 2 KP04 keypads for a more up-to-date KP04A. Not critical by any means, just curious as to why it has stopped working, I must have missed something.
Anyone put me on the right track?

I believe the F key used as fiunction was disabled some time ago, as it is easy for people to accidentally press the same key twice and thus execute a response.

Thanks Chiu
Probably hadn\'t noticed since I don\'t use it that often.
I can clean up the config file now.
