When you’re using a brush as an eraser, to paint with or in any tool that uses brushes, you can size the brush up or down using the keys on the keyboard. Continue to hold the it while you move the selection and let it go when the selection is in the correct place. Moving a selection is notoriously cumbersome without this keystroke: to move a selection while you are still drawing it, press and hold the Spacebar. Let go the Alt/Option key to return to the brush. Hold the Alt the key (Option on the Mac) to switch temporarily to the Eyedropper tool and click to select a new foreground color. When you’re working with a Photoshop brush and you want to sample a color from the image, instead of clicking the Eyedropper tool and then the Brush tool again, you can do it with a keystroke. To fill an empty layer with the current foreground or background color use Alt + Delete or Option + Backspace on the Mac to fill the layer with the Foreground color or Ctrl + Delete or Command + Backspace on the Mac or to fill with the Background color. This adds a flattened version of the image to the new layer but leaves the layers intact too.

Here’s how to have your cake and eat it too (or more accurately, flatten your layers and keep them too).Īdd a new empty layer to the top of the layer stack, click in it and press Ctrl + Alt + Shift + E (Command + Option + Shift +E on the Mac). Sometimes you need, for example, to flatten the layers in an image to sharpen the result but you don’t want to get rid of the layers either.
