When you use Adobe Photoshop day in and day out, certain things about its interface and workflow start to grate on you, like the inability to zoom while in the middle of a transform or applying Layer Effects. Much to my delight, Photoshop is also jam packed with hidden commands and modifier keys, which turned up a discovery today.
If you’re in the middle of a Transform or Layer Effects change and need to get your changes just right, you can adjust your view simply by holding the correct keys and using your mouse. On the Mac, hold Space and drag to pan around the background window. Command-Space-click on the document to zoom in, and Command-Option-Space-click to zoom out. Note that some of these key combos collide with the system-wide Spotlight commands, so you may consider remapping them in System Preferences, depending on your usage of each. Personally, I’ve moved Spotlight to Control-Space just to use these great hidden features of Photoshop.
