I want to create a key binding in Sublime Text 3 for the command Tools > Babel > Babel Transform.
I have used the menu item Preferences > Key Bindings to open the user keymap, and I have added this line:
{ "keys": ["ctrl+shift+b"], "command": "babel_transform" },
However, pressing Ctrl-Shift-B has no effect. If I use a different command (such as "prompt_open_folder"), the key binding words correctly, so I assume that it is the "babel_transform" command which I have got wrong.
How should I write this keymap line correctly?
