Curly brackets

I request Apple to add curly brackets in shapes for all iWork applications. These should be in two styles,

1. Single sided

2. Two sided (open and close) with an option to insert text in it.

I have to use these regularly in my Keynote presentations which I use to deliver my lectures.

I have also come across various other people facing the same problem.

At present I go a round about what of creating the shape in Microsoft Word and then copy as image in my presentations.

I have also come across various other people facing the same problem.

I hope Apple will do the needful.
