This change takes away the existing functionality where you could use CTRL+B to toggle bold. This would always add more text. For example, pressing the hotkey twice on 'hello' would result in:

=> hello
=> **hello**
=> ****hello****

Arguably, the first approach wasn't foolproof either, but this implementation is immediately broken.

Your changes appear to change the code to be indented with 2 characters instead of 4, which is the current convention of the file. I'd appreciate if you could make sure the file remains consistent.
