how to close a method/function on iPhone xCode?

when your project is getting bigger and bigger we have to look for ways to make it more easy to read.

The point is, I want to close all my functions using any key short code in my Xcode, let see the picture attached to understand what I mean:

(I cannot set any picture becuase I need more reputation...)

Well I mean:

  > - (void) process开发者_如何学C1 {

  }

If we press on the row on top left, the process will get closed. How can I use a key short code to close all my functions/methods on my class (.m)?

Thank you!
