simple way to make everything in your scene invisible?

in The Commons
Simple question: if its possible how can you select everything in the scene tab to be invisible? rather than take ages going down the list of things in the scene and clicking the eye symbol. Is there a way? thx.

Assign everything to a group or null.
K how?
select everything and at the top CREATE - new group
gottit. Thankyou guys :)
You can also Command-click the eye icon in the scene view for a parent object and all child items/bones will be hidden as well (presumably the windows-equiv shortcut would be ctrl-click).
Really... the amount of clicks I could have saved
Just tried it and it is indeed ctrl-click on windows - thanks, you just saved me lots of time :)
