> Ctrl + C to cancel a command in terminal but Cmd + C to copy text in terminal. Ok, then why Cmd + T to open a new tab in terminal instead of ctrl?

As a heavy terminal user this bothers me a lot..

Control+T and Control+C has very special use for the shell. I don't want a terminal "app" taking over those bindings for a misc feature.

I don't get why the Meta key is rarely used in Linux desktops.
