Ctrl and Mouse click

Oh man, I only want to drag the lettered file, but I don’t want the non lettered. I’m going to waste my time if I’m dragging the rest. Wait, there is a way!

By holding the CTRL key, and clicking the selected item, I can deselected, or selected again! For now, I’ll deselect the non lettered files. Ok, there we go! I’m dragging the files with one letters!

Try experimenting with the SHIFT key.
