Good day, dear friends. Imagine that you are concentrating on some kind of project in Photoshop. And then you finish, finished all the effects, painted and processed everything, and even. And then you notice that in the final image you can see a sickly flaw, which caught your eye sharply. Panic, the layers are merged. What to do? How to retouch? Several hours of work for a smark!
In fact, I hasten to calm you down. There is nothing wrong with that. You can go back one or several actions back to a certain point. And today I would like to tell you how to undo the last action in Photoshop and not worry if you messed up.
So let's go!
Cancel with hotkeys
The easiest way to go back a certain number of steps is to use keyboard shortcuts.
To undo the last action, press the key combination "CTRL + Z"... But this bundle works only with one last action, i.e. you can only go back one step. And if you press these keys again, you will return to where you started.
To undo several steps, you need to press the combination ALT + CTRL + Z... Then each press of this combination will undo the previous action until you return to the desired step, when everything was still good. Very fast and convenient.
Returning with the History panel
Consider another way to undo actions, namely the History window. How is this method convenient? The fact that you see what actions when you performed. Thus, you immediately choose which step to return to. Well, in general, let's see in practice.
This is how you can easily and conveniently return to some previous state of work. In addition, the "History" allows you to see how much the image has changed in comparison with the original after editing. To do this, just go back to the very top step. Have you looked? Now go back again to the last step.
How do you like the return? Useful thing? Still would. You definitely need to know this. And by the way, if you really want to know Photoshop well, then be sure to take a look. video course to work with him. The lessons are simply amazing, no water and everything is told in human language. Highly recommend.

Best regards, Dmitry Kostin.
Now we are going to take a look at a very useful feature present in Microsoft Office - the undo function. This feature allows you to save time when creating documents by automatically returning the document to its previous state.
In fact, the undo function (or simply Cancellation) is present, of course, not only in Excel or Word, but in general in any program designed to edit something. The process of creating any document in any program consists of a sequence of certain actions: printing text, moving pictures in a document, changing font parameters, and so on. If, when editing a document, you made a mistake and performed the wrong action, then you need to return the document to its previous state.
The mistake many users make is that they try to return "as it was" manually. In Microsoft Word courses, I had to deal with cases when, having accidentally deleted a large piece of text, the user started typing it again. And this despite the fact that the undo function was already known. Of course, this should not be done, since the creators of Word and Excel have already foreseen everything.
Remember: if the program is intended for editing a document (any!), then in it necessarily there is a cancellation of the operation!
How to cancel an operation
The button responsible for canceling the action is usually located on the toolbar of the main program window and looks like a curved arrow to the left. Also, there is usually a still curved arrow to the right nearby - it is responsible for repeating the canceled operation, or, in other words, for "cancellation cancellation"... Use the redo button if you undo more than you need to.
The operation undo and redo buttons correspond to the generally accepted keyboard shortcuts:
- Ctrl + Z- cancellation;
- Ctrl + Y- repeat ( cancellation of canceled);
These keyboard shortcuts are some of the most common in Windows and should be learned! Using keyboard shortcuts instead of toolbar buttons makes editing your document faster and saves you tons of time.
You can undo not only one (last) action, but several in a row. Sometimes it is even possible from the very creation of the document. The same applies to redo - if, for example, the last 10 operations were canceled, then you can also return them. However, there is one important thing to remember:
if you close the document, then the entire history of changes is lost!
In Excel, undo works in exactly the same way. But it is worth remembering that in some versions of Excel there is one feature that is characteristic only for this program: when you save a document, the history of its modification is deleted and nothing can be undone. This can be seen from how the undo button on the program toolbar is deactivated.
There was an important part of the article, but without JavaScript it is not visible!
When not to use cancellation
You can only undo what is change document! Some operations are not edit operations and cannot be undone.
Remember! Text selection not is editing the document and is not canceled via the undo function. The selection of the text is simply reset!
Many times I noticed in Microsoft Office courses exactly attempts to "cancel" the selected text, that is, to remove the selection through the cancellation of the action. This is wrong, because the selection of a block of text does not lead to a change in the document, which means that the cancellation has nothing to do with it. If you don't believe me, then open any existing document with text and select part of the text - the cancel button will remain inactive, i.e. there is nothing to cancel.
Video tutorial on undoing actions in Word and Excel
The video shows examples of various cases of undoing actions for editing documents.
Let's sum up
Remember keyboard shortcuts Ctrl + Z and Ctrl + Y, as well as their corresponding buttons on the toolbar. Using the undo operation allows not only saving time when editing a document, but also avoiding errors when returning a document to one of the previous states.
7 December 2013 Vladimir Main page »Your computer Views: 32001Hello, friends. I am glad to welcome all of you to the pages of the Spectr-rv.ru blog. Today I want to tell novice users how you can undo the last action when working on a computer. This is the key combination Ctrl + Z. With this combination, you can easily and easily undo the last operation performed.
Undoing the last action (Ctrl + Z combination) can be very useful in many cases. For example, in a hurry, you moved a file to the wrong place. Or you moved the file instead of copying it. Or they deleted one file instead of the other.
You can, of course, find the incorrectly moved file and put it back in place. You can also find the material you deleted by mistake in the Recycle Bin and restore it. But it's much easier to press Ctrl + Z.
According to this combination, everything that was incorrectly moved back to its place and everything that was mistakenly deleted is restored. By undoing the last action (keyboard shortcut Ctrl + Z), you can also return the original file name if you renamed it incorrectly.
An obstacle to recovering a deleted file using the Ctrl + Z keys may be emptying the trash after executing an incorrect command. And also, it is impossible in this way to recover a file that was permanently deleted by the command Shift + Del.
In text and image editors, the analogue of the Ctrl + Z command is the curved arrow button shown in the figure below.

That's all I wanted to tell you about how you can undo the last action if you are not satisfied with the result. You learned that the easiest way is to use the keyboard shortcut Ctrl + Z. I hope you enjoyed the article. Good luck!

How to undo an action on a computer

How do I undo the last action on my computer? Operating system recovery
Almost every user has come across a situation where certain actions performed on the computer, instead of the expected result, cause harm, and I want to understand how to undo the last action on the computer. For example, it can be downloading various programs that have been infected with viruses or something else.
Microsoft realized a long time ago that the main enemy of the computer and the operating system is far from some hacker or some other intruder, but the user himself, because it is by their actions that people most often cause their devices to malfunction. That is why the function of how to undo the last action on the computer was introduced, and it is called "Restoring the operating system".
What is it?
Operating system recovery is a feature that allows you to roll back your computer to a specific date when its characteristics and data were saved. It should be noted that this data can be saved both automatically and manually by the user, depending on how this function was configured. 
The advantage of this method is that it allows you to completely remove all the negative actions that you performed on your computer for a certain time. But, considering how to undo the last action on the computer, it often fails to use it, because it cancels several actions performed on the computer at the same time, regardless of whether they were harmful.
Automatically and manually
As mentioned above, the system can be saved either manually by the user or automatically. In professional circles, this is called "saving a backup", and it must be done, since it is impossible to undo the last action on the computer without it. 
To configure this in Windows 7, you need to go to the path: "Control Panel"> "Recovery"> "File recovery"> "Configure backup". Here you will need to select the basic parameters and start archiving. In particular, you can independently choose whether to save only certain folders, or even provide a choice of folders to the operating system in order to save the most important information in the first place.
What to choose?
The advantage of automatic copying is convenience, but for it you need to allocate a large amount of free space on your hard disk, and often it is not suitable, since it is still possible to undo all actions on the computer for the last day, but for a month or a week it is already more difficult.
That is why it is recommended to perform archiving exclusively by hand. In particular, it is especially recommended by experts for Windows 8, since you need to undo recent actions on a Windows 8 computer more often. To configure it in this system, you will need to go to the "Backup and Restore" section through the "Control Panel", then select "Create a system image" and follow all the instructions of the wizard.
Data recovery is important too
It is worth noting that, among other things, backup is highly recommended if you store some important information on your computer. Thus, if some malfunction occurs during the operation of your equipment, and you lose all data stored on the hard drive, a backup copy will allow you to extremely quickly return any files you need in just a few minutes without the involvement of outside specialists, which will save you not only nerves and time, but also money.

How to undo recent actions on a computer
Working at a computer, each user sometimes makes erroneous actions that he would like to immediately cancel. Fortunately, this is not a problem and there is one great feature that can help you with this.
Most programs have an Undo command that undoes any recent actions or changes in the current project. If the last action was to add or insert text into the document, then using the command you can undo / delete and return to the original version. If the last change was deleting something, you can restore it accordingly. It can also come in handy when you accidentally overwrite a large chunk of a document. Indeed, knowing and using this function is a great relief for many users.
The Undo function is most often found in the Edit or Edit menu.
Many programs have an Undo button on the toolbar, which usually resembles a curved left-pointing arrow, such as in Google or Word documents.
Likewise, you can press Ctrl + Z (or Command + Z on Mac) to undo recent actions on your computer.
As a rule, some programs use the Undo function to track not only the most recent actions, but also a whole series (history) of the most recent changes. For example, you inserted a picture into a document and entered text over the picture, and then used the Undo command once - this will undo the most recent action. That is, in this example, you will delete the text over the picture that you typed, and using the command a second time, you will delete the picture that you inserted. Keep in mind that the history of changes is only saved while the program is open. If you close the document (whether you saved it or not) and reopen it, you cannot undo your previous actions.
Many programs also have a Redo (or Forward) function that returns what you undone with the Undo command.
These commands are used in almost all existing programs, including text editors, graphic editors, email clients, file management programs, etc. It is a versatile function in the field of computer software. Once you get used to using these helpful commands, you no longer need to worry about getting messed up by simple mistakes.

That, in fact, is all, from this short article you learned how to undo the last action in the Word, which means that you can always correct the mistake in time.
We are glad that we were able to help you solve the problem.
When using a computer, users often have a situation when some action was performed accidentally or incorrectly, for example, deleting or renaming files. Especially for such cases, the developers of the Windows operating system have come up with a convenient function that undoes the last action. In addition, this process is carried out with the help of other tools. In this article, we will describe in detail the methods of undoing the last actions on the computer.
Usually, accidentally performed operations on a PC can be returned using a special hotkey, but this manipulation will not always work. Therefore, you will have to resort to implementing certain instructions through built-in utilities or special software. Let's take a closer look at all of these methods.
Method 1: Built-in Windows Function
As mentioned above, Windows has a built-in function that undoes the last action. It is activated using a hotkey Ctrl + Z or via the pop-up menu. If, for example, you accidentally renamed the file in a wrong way, just hold down the above combination or right-click on a free area and select "Undo rename".
This keyboard shortcut also works when you move a file to the trash can. In the pop-up menu, click on the item "Undo delete"... If the data has been permanently deleted, you should use special software or built-in utility. Below we will discuss this recovery method in detail.
Method 2: Undoing actions in programs
Many users actively use various software in their work at the computer, for example, for editing text and images. In such programs, the standard keyboard shortcut most often works Ctrl + Z however, they still have built-in tools for undoing an action. The most popular text editor is. There is a special button on the panel at the top that cancels the input. Read more about undoing actions in Word in our article at the link below.
It is worth paying attention to graphic editors. Let's take as an example. In it in the tab "Editing" you'll find a number of tools and hotkeys to step back, undo edits, and more. We have an article on our website that describes this process in detail. Read it at the link below.
Almost all such software contains tools that perform undoing actions. You just need to carefully study the interface and familiarize yourself with the hotkeys.
Method 3: System Restore
If files are permanently deleted, they can be restored using the built-in Windows tool or using special software. System files are returned by separate methods, via the command line or manually. You can find detailed instructions in our article at the link below.
The easiest way to recover ordinary data is through third-party software. They allow you to scan specific partitions of your hard drive and return only the information you need. Check out the list of the best representatives of such software in the article below.
Sometimes some manipulation leads to system malfunctions, so you have to use a built-in or third-party tool. These tools create a backup of Windows in advance, and restore it if necessary.
Almost all changes made to images can be undone. You can undo the last action by choosing Edit → Undo from the image menu, but this operation is used so often that it is worth remembering the keyboard shortcut Ctrl +Z .
Cancellation itself may be canceled. After canceling the action, you can return it by selecting Edit → Redo in the image menu, or using the shortcut key, Ctrl +Y... This is often useful in assessing the effect of an action by repeatedly undoing and redoing it. This usually happens very quickly, without wasting resources or changing the undo history, so there is no harm in doing this.
If you frequently use undo and redo many steps at a time, it may be more convenient to work with the Undo History dialog - a dockable pane that shows small thumbnails of each point in the undo history, allowing you to move back or forward to the point you click on.
Undo is performed on an image-specific basis: the "Undo History" is one of the components of an image. GIMP allocates a certain amount of memory to each image for this purpose. You can customize your Preferences to increase or decrease the amount, using the page of the Preferences dialog. There are two important variables: the minimal number of undo levels , which GIMP will maintain regardless of how much memory they consume, and the maximum undo memory, beyond which GIMP will begin to delete the oldest items from the Undo History.
Implementing action history in GIMP is quite complex. Many operations (such as changing the visibility of a layer) require very little memory for possible undo, so you can perform a large number of them before they start to disappear from the history of actions. Some operations (and again changing layer visibility) are compressed, therefore, executing them several times in a row produces only one point in the history of actions. However, other operations consume a lot of memory for possible cancellation. Almost any filter can be used as an example: since filters are implemented as extensions, the GIMP kernel cannot know for certain what they have changed. Thus, there is no other way to undo such an action other than remembering the contents of the affected layer before and after the operation. You can perform a limited number of such operations before they are removed from the activity history.
3.1. Noncancellable operations
Most of the actions that change the image can be undone. But some cannot be undone. Operations such as saving an image to a file, duplicating an image, copying an image, copying a part of an image to the clipboard, etc. This also includes operations involving influencing the display without changing the image data. The most significant example is display scaling. However, there are exceptions: toggling the visibility of the quick mask can be canceled if the image data has not changed between toggles.
There are several important actions that change the image but cannot be undone.
Closing the image
The Undo History is a component of the image, so when the image is closed and all of its resources are freed, the Undo History is gone. Because of this, unless the image has not been modified since the last time it was saved, GIMP always asks you to confirm that you really want to close the image. (You can disable this in the page of the Preferences dialog; if you do, you are assuming responsibility for thinking about what you are doing.)
Returning an image"Return" means to reload the image from the file. The GIMP does this by closing the image and creating a new image, thereby losing the undo history. For this reason, if the image has changed, the GIMP will always ask you for confirmation before returning.
Fragments of actionsSome tools require a complex set of manipulations to be performed before using them, but they only allow undoing entire operations instead of individual elements. For example, Scissors allows you to create closed paths by clicking on various points in an image and then clicking inside the path to create a selection. You cannot undo individual clicks: undo after completion will take you back to the starting point. In another example, when you work with the Type tool, you cannot undo individual letters, change font, etc .: undo after completing the operations will delete the newly created text layer.
Filters, and other actions performed by plugins or scripts, can be undone just like actions implemented by the GIMP core, but provided that they correctly use the GIMP undo functions. If the code is incorrect, the add-on can potentially mess up the undo history, so that not only the add-on's actions, but also the previous actions can no longer be undone correctly. All scripts and add-ons supplied with the GIMP work reliably correctly, however there are obviously no guarantees for add-ons obtained from other sources. Also, even if the code is correct, undoing an add-on while it is running can sometimes leave the undo history corrupted, so it's best to avoid this unless you accidentally do something with bad consequences.
