It often happens that users inadvertently make changes to a document that need to be reverted. In a word processor Microsoft Word it is possible to undo an action and redo the last action. The first command is intended to undo the last actions of the user, and the second - to again, without performing these actions, cancel the undo of actions. Unclear? Then let's understand these extremely important functions with a simple example.

Working with a document in the Microsoft Word word processor is like scrolling through a film - every user action, whether it's inserting an image, typing a character, or deleting it, is like a frame in a movie. And the Microsoft Word program records these frames. At any time, the user can go back a certain number of frames, and then return to the last executed frame.

In Microsoft Word, there are two options for working with the user's undo and redo functions:

• first- using keyboard shortcuts. To undo the last user action, use the Ctrl+Z key combination, and to redo already performed and undone actions, use the Ctrl+Y combination;
• second- use of buttons specially designed for this purpose on the quick access panel, which are located in the upper left part of the main working window Microsoft programs word. In this case, to undo the last action of the user, click the button, and to repeat the actions already performed and previously undone, click the button.

Word processor Microsoft Word offers users a huge functionality for working with documents of any size and complexity. Mastering the techniques described in this article will help you work with documents several times more efficiently without being distracted by formatting, and this will guarantee the user's concentration on the content. Below are a few basic tips to follow when moving through a document.

• Use different document display modes to solve different tasks. In each of the modes, unnecessary interface elements are specially removed and an emphasis is placed on those elements that help solve specific tasks for each type.
• Use "hot" keys. By learning how to operate with keyboard shortcuts, you can significantly speed up your work with a word processor.
• Copy and cut document content to move and duplicate content in different places in the document. If parts of the document are similar, it's easier to create a copy and change a small part, rather than rewriting the whole thing.
• Use the clipboard to work with multiple sections of document content at once. Even if you change the locations of two document fragments, the clipboard will reduce the number of operations.
• Use the Navigation panel to view and edit the structure of the future document. The unique feature of the new Microsoft versions Word allows you to edit the structure of your document with a simple click of the mouse.
• Use the search bar Navigation (Navigation) to search for simple expressions and dialog box Find and Replace (Find and Replace) for difficult cases.

Almost every user has encountered a situation where certain actions performed on the computer, instead of the expected result, are harmful, and I want to understand how to cancel 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 operating system is far from some hacker or some other attacker, 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?

Restoring the operating system 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 exactly 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, when considering how to undo the last action on the computer, it often fails to be used, because it undoes several actions performed on the computer at the same time, regardless of whether they were harmful.

Automatic and manual

As mentioned above, the system can be saved both manually by the user and automatically. In professional circles, this is called "saving a backup", and it is necessary to do it, since it is impossible to undo the last action on the computer without it.

To configure this in Windows 7, you need to go along the path: “Control Panel”> “Recovery”> “File Recovery”> “Configure backup". Here you will need to select the main parameters and start archiving. In particular, you can independently choose whether to save only certain folders or even give the operating system a choice of folders so that the most important information is saved first.

What to choose?

The advantage of automatic copying is convenience, but you need to allocate a large number of free space on the hard drive, and often it is not suitable, since it is still possible to undo all actions on the computer for the last day, but it’s already more difficult for a month or a week.

That is why it is recommended to carry out archiving exclusively manually. In particular, this is especially recommended by experts for Windows 8, since undoing the last actions on Windows computer 8 is required mostly more frequently. To configure it on 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, it is highly recommended if you store some kind of important information. Thus, if some kind of malfunction occurs during the operation of your equipment, and you lose all data stored on the hard drive, backup copy will allow you to extremely quickly return any files you need in just a few minutes without involving specialists from outside, which will save you not only nerves and time, but also money.

This article describes three operations that will help you undo erroneous actions and improve editing efficiency.

Cancel actions

You can undo almost all commands done in Excel with the command Cancel located on the Quick Access Toolbar. The Quick Access Toolbar is typically displayed to the left of the Excel title bar. You can also click ctrl+z to cancel actions.

Select Cancel, after executing some command by mistake, and this command will be canceled as if you never executed it at all. You can undo the result of the last 100 commands executed by pressing the button Cancel many times.

However, some actions cannot be undone. All commands executed with the button File, such as saving a workbook, cannot be undone. If you click on the arrow button to the right of the button Cancel, you will see a list of recent commands that can be undone (Fig. 6.1). You can select a set of such commands at once to undo several actions with one click. The figure highlights seven actions.

Keep in mind that you cannot undo the effect of running a macro. In fact, running a macro that changes a sheet erases all undo information. This tangible disadvantage of Excel is not in Microsoft Word.

Action return

The Redo button (located to the right of the Undo button on the Quick Access Toolbar) essentially cancels the Undo command. If you have undone too many actions, you can click the Redo button (or click ctrl+y or F4) to return commands that have been undone.

Action repeat

You can repeat many operations by pressing ctrl+y or F4. This command simply repeats the last action. However, if the last operation was an Undo operation, then the result of its action is undone (as described in the previous section).

Repetition of commands can be useful in terms of saving time. I'll give you an example. You could apply many formatting settings (set font size, bold, background color, and frame color) to a cell using the Format Cells dialog box. After closing the dialog box, you can easily set similar formatting settings for other cells or ranges by pressing Ctrl+Y. Or we may need to insert blank lines at certain places on the sheet. To do this, run the command Home → Cells → Insert → Insert rows per sheet once, then position the cursor in the cell where you want to insert the next line, and press ctrl+y to repeat the insert row command.

Excel also has a button Repeat, but it's usually not available. Regardless, let's add it to the Quick Access Toolbar.

1. Click right click mouse on the Quick Access Toolbar and in the appeared context menu select Customizing the Quick Access Toolbar. As a result, a dialog box will open. Excel Options tab Quick Access Toolbar.
2. Drop Select teams from select item Frequently used commands.
3. From the list of commands select Repeat.
4. Click the button Add to add the selected command to the Quick Access Toolbar.
5. Click OK to close the dialog Excel Options.

You may ask why add a button at all Repeat to the Quick Access Toolbar if you can use a keyboard shortcut ctrl+y. First, when you move the mouse pointer over this button, Excel will display a description of the repeated operation (Fig. 6.2). Second, the button Repeat becomes inactive if you cannot repeat the last command. - a kind of visual signal that will help to avoid unnecessary attempts to repeat what simply cannot be repeated.

Unfortunately, the retry function is not always reliable. In some cases, you may find that pressing ctrl+y does not give any effect (although it should). In other situations, pressing ctrl+y can repeat the command you ran before the previous command.
