We have mentioned Ctrl + c before, but here are ALL the keyboard shortcuts for both Windows and Macs. A new one on me was Ctrl+Shift+v which will paste something but without any formating - something I often do, for example if copying something from a webpage into a Label.
The "T2" image above is a label with just a picture in it. I added it simply by dragging and dropping. Below is a video explaining how to do this. I will show how you put a video into a label at a future date.
