I'm using Adobe InDesign (CC 2014) to layout a photo book. I've created a frame, and placed an image inside it. I want to resize the image and drag it around to frame it nicely.I know that you can select `Direct Selection Tool` and resize the image by dragging the box handles, or by changing the size on the toolbar. Is there a keyboard key modifier that I can hold down and scroll my mouse/trackpad to dynamically zoom the image within the frame? In a document with dozens of pictures, this would save a lot of time.
Right click on your image and choose to fit the frame proportionally to the image in the frame. There is a keyboard shortcut but it changes based on your OS. It will show you the shortcut in the menu when you right click.
