§ key - can't assign to activate visor

On my MBP i can assing § to visor activation key. But on imac i can't ( only beep sound ). Only cmd+§ works. On mbp i can do this without problem.

i try to copy terminal and total terminal *.plist's between mac's but nothing. Hot key does not changing.

if i close totalterminal (on MBP) - § key works as normal § sign.

p.s. this hotkey i see in menu on MBP

and this in prefs.

One week I can't remember what i made in past to do this works with only § key on my MBP :(
