Need to change that key binding... thanks to the US-centric take we've had on keyboards since the TTY days, that key combination doesn't make sense on a Portuguese keyboard.
They did, they're using Ctrl+ç, which is a nice way to use an otherwise useless key for programming, but hardly memorable or ergonomic for me - I'll go and use Ctrl-Shift-T as well, which is what I use in Openbox ;)
