§ 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 :(

The issue names no source files or tests. Start by reproducing the visor activation key behavior on the MacBook Pro and iMac, then compare the TotalTerminal hotkey shown in the menu and preferences. Done means the § key activates the visor on the iMac without requiring Command, while still producing § when TotalTerminal is closed.
