Just a quick post for today, with my most used shortcuts. I can’t recommend these enough — they work everywhere, Photoshop, Camera Raw, Lightroom, and in places where other shortcuts don’t necessarily work, like in Photoshop filters.
First, the left bracket key [ and right bracket key ] for decreasing and increasing brush size … paint brush, healing brush, clone stamp, adjustment brush, spot removal tool, eraser, etc, etc.. Don’t waste your time going into brush menus for this! Similarly, shift [ and shift ] control how soft or hard your brush is, in 20% increments.
Second, for zooming in and out on an image, I use Ctl/Cmd + and Ctl/Cmd -. Again, in all of these programs. Holding the space bar down gives you the hand tool so that you can click and drag around in the image to get to the part you want to see. (Hold the space bar down the entire time).
