INS key on macbook and vuurmuur

[admin lewis]

Hi
I have installed fedora on my macbook. Everythings work well but I
have a problem with vuurmuur software.
vuurmuur is a ncurses iptables front-end so that it run on terminal.
To insert data on vuurmuur I have to press INS key on my macbook ...
but it has NO  INS key.
On gnome INS is mapped as FN+DEL and it works very well on vim, bash
etc. But it wont work on vuurmuur. How can I solve this problem ?
thanks luigi
