Switching between the tools in InDesign can make you lose valuable time and make your arm hurt! My left hand is always on my keyboard, so I use my modifier keys to switch between my tools.
Hold Command and Spacebar (mac) | CTRL and Spacebar (win) while you’re on any tool. The zoom tool will be temporarily active. Use the tool by either a single click or a click and drag around the area you want to see closer.
Release your keys on the keyboard and you’ll return to the tool you were previously on.
Keyboard Shortcuts:
Command and the “+” key | CTRL and the “+” key – will zoom into the selected item in both InDesign and Illustrator (2017)
Command and the “-” key | CTRL and the “-” key – will zoom out
Command and the “0” key | CTRL and the “0” key – will fit the page into the window (don’t use the “0″ key on the numeric keypad.)
Command, Option and the “0” key | CTRL, Alt and the “0” key – will fit the spread (InDesign) or all the art boards (Illustrator) in the window.
Happy Zooming!
