Hello, dear habradrug! This article lists the 25 most useful shortcut keys in Photoshop that you can use to speed up your work. Some of them are rarely mentioned, some are used quite often, and some are generally only available in Photoshop CS5. I hope that each of you will find new and useful shortcuts in this article. So let's get started!

1. Move-approximation
Command / Ctrl + Space + Click / Move the cursor to the right or left. This is the fastest way to zoom, but this shortcut works only in CS5 and only with the GPU turned on.
2. HUD Pipette tool
Select the eyedropper tool and hold down Alt + Shift + Right Click (Win) or Control + Option + Cmd + Click (Mac). A window with a color palette will appear.

3. Review the entire document.
Hold H + Click. Works perfectly with high resolution pictures. This is a quick way to fit the whole picture to the window size.
4. Brush size and stiffness
Select the Brush tool and hold down Ctrl + Alt + Right click (Win) or Control + Option + Click (Mac). Move the cursor left or right to change the size of the brush, and up or down to change the stiffness. The CS5 works with both size and stiffness. In CS4, only with size.
