When working on a computer, the user can make a mistake: enter incorrect data into a spreadsheet or accidentally delete an entire section from a text document; in Adobe Photoshop, fill a lovingly created collage with black color or remove all shortcuts from the Desktop using an unknown method.
Instructions
Step 1
To undo an erroneous action in a document created in MS Word, select the Undo command from the Edit menu. The same result can be achieved using the Alt + Backspace hotkeys. If you suddenly realized that the action was correct, and in vain you canceled it, apply the combination Ctrl + Y.
Step 2
On the Quick Access Toolbar, find the Undo button. If you want to undo more than one action at once, click the down arrow next to this button to expand the list of recent actions taken. While holding down the left mouse button, mark unnecessary operations with the cursor and release the key. The same result can be achieved using the keyboard shortcut Ctrl + Alt + Z.
Step 3
There is a Redo button next to Undo on the Quick Access Toolbar. It returns deleted steps. Its action is duplicated by the F4 function key. If the Undo button has not been used, the Revert will be grayed out.
Step 4
To undo actions in MS Excel, you also use the Undo command from the Edit menu, the Undo button on the Quick Access Toolbar and the Alt + Backspace and Ctrl + Z shortcuts. To return erroneously canceled actions, the same tools are used as in MS Word.
Step 5
In Adobe Photoshop, in this situation, it is convenient to use the shortcut keys Ctrl + Alt + Z and the Step Backward command from the Edit menu. To revert an erroneously canceled action, use the Step Forward command and the Shift + Ctrl + Z combination.
Step 6
In addition to the standard keys and commands, Photoshop has a handy History option. Find it in the Window menu and check the box. Find the unnecessary action on the History panel, pick it up with the mouse and drag it to the trash can icon at the bottom of the panel. To undo all changes, click on the image icon at the very top of the list.
Step 7
If you have made any fatal changes in the operating system, the "System Restore" service will help you get it back to work. Open the program launch window with the Win + R combination and enter the msconfig command in the "Open" line. Go to the "Service" tab, mark "System Restore" in the list and click "Run". Select the date that is closest to the date when the erroneous actions were taken.
