If you're talking about just hiding text you can use the "narrow" function. 
You highlight a region, type C-x n n and everything not highlighted 
disappears. To bring everything back you "widen" it with C-x n w.

It can be handy to confine a macro or search to just a certain area. It 
might also be good if you worked in an office where people could look over 
your shoulder at privileged information.

I've found it's a little bit fragile. Sometimes it will widen all by itself 
so I always check the mode line when I'm about to do something radical.
