[O] Making org-agenda-list hide items scheduled for the future

[Michael Hoffman]

I use the weekly/daily agenda and want to be able to use the SCHEDULED 
keyword to hide items until the scheduled time comes up. I don't want to 
think about them until then. How can I set up org-agenda-list to do this?

This is the list of agenda items, not the TODO list. I already have 
org-agenda-todo-ignore-scheduled set to future. It does not help.

I am using org-mode 8.2.4, Emacs 24.3.2, CentOS Linux 6.5.
