[Orgmode] export TODO keyword

[Rares Pop]

Hello,

sorry for the beautifier question. 

I'm trying to export an org document with some TODO tasks to a PDF file.

And I get the output in the PDF file for the TODO keyword like this:

 {TODO}

But i want it simple

TODO or [TODO].

I don't want to have those curly brackets at the beginning and the end of the TODO keyword.

Thank you very much for the help,

Rares
