A number of family members use mIRC to visit their favorite chat groups. We keep the #channels open and they are tiled.

I would like to be able to leave my chat room open but 'lock' the keyboard for that channel if I'm going to be away from the computer.
This way there wouldn't be the occasional error when someone typed into the wrong chat room screen.
I've looked at the 'lock' feature and that isn't exactly what I want.
I can't 'devoice' myself as I'm not an 'op' and my room is not moderated.

Can a hot key be created to disable typing into a channel and a password or hotkey to reenable typing.

I use mIRC every day, as do my family members and we are always forgetting and typing into the wrong rooms.

As always, Please and thank you
