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

It is possible to overwrite the default bindings of installed packages by creating a custom default bindings file.

For example I want ctrl-T to transpose, so I have modified default bindings for CTags:

• Copy c:\Users\USER\appdata\Roaming\Sublime Text 3\Installed Packages\CTags.CTags.sublime-package to tmp.zip
• From the zip file extract Default.sublime-keymap to c:\Users\USER\appdata\Roaming\Sublime Text 3\Packages\CTags\
• Modify or remove the binding from this file.

If the package is updated the custom default binding file is kept, so your bindings are kept and any new bindings will have to be updated manually.
