Locking an item to not be selected?

So, I'm wondering is there a way to "lock" an item so it cannot be selected, nor have that yellow highlight whenever you move your mouse across it.
Like for instance, say I load in a house or a large city scene, and I want to mess with posing figures without accidentally selecting the scene, or having that distracting yellow highlight as I'm moving around the scene.
so is there a way to lock a scene/building so it can't be selected/highlighted?

firstly you can turn OFF the Yellow highlighting by choosing a selecting tool and go to the Draw Settings Pane and change Highlight Style to Bounding Box Only.
To lock an object from being selected go to the Scene Pane, next to the object and you have on the extreme left an Eye, Arrow and a Tick. Click the Tick to change to a Cross and now you cannot select the object in the Viewport window.
