Selecting issues

Hi, i just wanted to ask you a quick question: can somebody explain me how to select multiple things at the same time? Like if i have 2 boxes, and i left-click on one of them that box would be selected, but only one at time. How can i do if i want to select both of them at the same time? Thank you very much to anybody that will help me :slight_smile:

Hold Ctrl + Left Mouse Click on the objects that you want to select :slight_smile:
