How to unbind a key binding in Sublime Text 2?

Question

I have a habit of hitting CTRL+T to open a new tab in ST2. However this invokes the transpose function. I could map the new_file command t

Answer 1

{ "keys": ["ctrl+-"], "command": "noop" }

Binding a key to a no-operation or anything which wouldn't carry a command behavior, such as "hello", should work.

This would also keep the body of the binding if you change your mind in the future.
