Filtering the BP Activity Loop

Hi: I'd like to filter the activity loop on my BP installation (version 1.2.10) so that it shows status updates only - or at least as the default view. I've found a couple places in the BP Codex where this is discussed; but none of the solutions mentioned there seem to work. (My gut tells me that the syntax there is wrong.)

I'm sure this is easy for one of you ladies or gents. Your feedback would be much appreciated. Thanks in advance --
