Press the Tab key to switch between showing and hiding all control panels, including the toolbox. If you press Shift+Tab, the toolbox will not be affected, only other control panels will be displayed or hidden.

6. Quickly restore the default values

Some friends who are not good at Photoshop have adjusted the satisfactory effect after many twists and turns, and found that the original default effect is the best. This is a plot against me, I regret it! How to restore the default values? Try clicking the tool icon on the options bar, and then select Reset Tool or Reset All Tools from the context menu.

7. Free control of size

The shortcut key of the zoom tool is "Z", while "Ctrl ++ SPACEBAR" is a zoom tool, and "Alt ++ SPACEBAR" is a zoom tool, but it can only be zoomed by clicking with the mouse. Press Ctrl+"+ "+ "and"-"keys to enlarge and reduce the image respectively; Ctrl+Alt+"+ "and Ctrl+Alt+"-" can automatically adjust the window for full-screen zoom display. With this tool, no matter what percentage the picture is displayed, you can browse it in full screen! If you want to automatically adjust the window according to the picture size when using the zoom tool, you can click the "Full Canvas Display" option in the zoom tool property bar.

8. When using a non-hand tool, hold down the space bar, which can be converted into a hand tool to move the visible range of the image in the window.

If you press the Shift key first and then press the arrow keys, you can move the image 10 pixels at a time. Alt dragging the selection will move the copy of the selection.

14. When using the magnetic lasso tool or the magnetic pen tool, press the "["or "]" key to increase or decrease the sampling width in real time (in the options panel).

15. It is very convenient to measure the distance with a measuring tool (especially on the diagonal), and you can also use it to measure the angle (just like a protractor). On the premise that the information panel is visible, select the measuring tool, click and drag a straight line, and hold down the Alt key to drag the second straight line from the node of the first straight line, so that the included angle between the two straight lines and the length of the straight line are displayed on the information panel.

The color values before and after the change are displayed next to the sampling point number on the information panel. You can define the color mode of sampling points through the pop-up menu on the information panel. To add a new sampling point, simply click anywhere on the canvas with the color sampler tool, and then hold down the Alt key to remove the sampling point. However, a maximum of four color sampling points can be placed on a picture. When a dialog box pops up in Photoshop (such as color code command, curve command, etc. ), you must hold down the Shift key and click again to add a new sampling point, and hold down the Alt+Shift key to click to subtract a sampling point.

18. Everyone must have used cutting tools, and you must have encountered this situation; When you adjust the clipping grip and the clipping box is close to the image boundary, the clipping box will automatically stick to the edge of the image, making it impossible for you to clip the image accurately.

Replication skill

19. Hold down the Ctrl+Alt key and drag the mouse to copy the contents of the current layer or selection.

Hold down Alt and drag a step in an action to copy it into another action.

Selection skill

30. When dragging the selection area or layer from one document to another, hold down the Shift key to center it on the target document. If the size (dimensions) of the source document and the target document are the same, the dragged element will be placed in the same position as the source document (instead of the center of the canvas). If the target document contains a selection, the dragged element will be placed in the center of the selection.
