Question: I'm having trouble writing { } and [ ] brackets on Atom text editor.
My keyboard is setup on Croatian, I've tried to add a keyboard shortcut but it doesn't work.

Any suggestions?

Answer: 
You can unset key binding for `Ctrl+Alt+B` like this:

```
'atom-text-editor':
  'ctrl-alt-b': 'unset!'

```

Just find a key binding that you want to remove, copy it and set it's value to "unset!"

Here is my full mapping:

```
'atom-text-editor':
  'ctrl-alt-b': 'unset!'
  'ctrl-alt-f': 'unset!'

'.platform-win32 atom-text-editor':
  'ctrl-alt-.': 'unset!'

'atom-workspace atom-text-editor:not([mini])':
  'ctrl-alt-f': 'unset!'

'.platform-win32, .platform-linux':
  'ctrl-alt-f': 'unset!'

'.platform-win32 atom-text-editor, .platform-linux atom-text-editor':
  'ctrl-alt-q': 'unset!'

```
After I unset above mentioned keybindings, I just figured out if you press `ALTGr` + `7` keys it would produce open and close curly braces, using hungarian keyboard.
