   Aha! This setting can be found in the GConf editor (registry):

Apps->gnome-terminal->keybindings

   Setting to 'disabled' turned it off. This disabled F1 for all 
'gnome-terminal's that I opened after changing the setting. The setting 
is applied -on-the-fly- and is immediately reflected in (all) open 
gnome-terminals.

   You can script (php->exec/system) this, take a look:

http://webnesbay.com/configure-your-gnome-desktop-environment-using-gconftool-in-ubuntu-linux/

   That should do what you want... as for the actual grabbing of the 
keys, I don't have (php)ncurses set up on this machine (or one that's 
handy at the moment) to try.

   There are some user notes here you may be interested in:
