Is there an option to clear up clutter on the views in hammer?

I dont know how to word it, that is why I cant find my answer. But my grid is so cluttered I cant edit because I cant see. Is there an option I can turn on to only edit in the area?

Visgrouping and Quick Hide. You Quick Hide by selecting the objects you want to hide and press H. To visgroup select the objects you want to visgroup, open up properties, go to visgroups and put them in a group.

How do I unhide them?

Hit U.

Also, if you want to keep things tidy, you may want to create your own visgroups.
