How to erase multiple entities in one pass

As per some Sketch-up videos on erasing, I noticed some are able to erase several in one pass. I am unable to do it by selecting before issuing the Erase command. How is it done? Holding the left mouse button and crossing my cursor over is not what I am looking for.

What are you looking for, then? You can select multiple entities and hit the Delete key.

Thanks! I didn’t think of that!
