Ive been using InDesign for the passed three years. Ive gotten pretty good at the key commands. I usally work on a mac pc but I just downloaded Adobe Creative Cloud onto my MacBook Pro. I was working in InDesign and went to resize an image, to keep the proportions I held shift on my keyboard but the picture got out of proportion. I then tried to copy a shape by holding option and dragging the shape down, but that key command also didnt work. Why is this? Do I have to change something in my preferences?
