Question

Not a long ago I started to learn Mathematica – i.e. I’m novice. Usually I code in text editors with auto close of brackets like Gedit,Notepad++,Qt IDE etc.
It’s very convenient when you are not obliged to watch over brackets.
But my attempts to find similar functionality in Mathematica weren’t successful. I can’t believe that such a powerful tool doesn’t have such simple thing. Does anyone know how to autocomplete brackets?

You could experiment with something like:

SetOptions[InputNotebook[], 
 InputAutoReplacements -> {"[" -> "[\[SelectionPlaceholder]]", 
   "{" -> "{\[SelectionPlaceholder]}", 
   "(" -> "(\[SelectionPlaceholder])"}]

Note that the replacement doesn’t happen until you type a character after the opening bracket. If you like the result you can then apply this more globally.
