I installed it throught the Scripts Manager, but nothing happens when I press CTRL and T together
It doesn't work. When i press CTRL+T It just brings up tabs.
Just a minor problem: the key combination doesn't work if NumLock, CapsLock, or ScrollLock is on, because they affect the value of modifier. Have you considered using event.register(event.keypress, [handler]) instead of tpt.register_keypress([handler]) (which is deprecated in v0.94)?
