Let's have a good understanding of the keyboard, and by the way, common shortcut keys.

This kind of thing, keyboard, is familiar to everyone. Because it's so common, we don't seem to know much about keyboards. So, I think it's better to know the keyboard well. (The PC used in the example in this paper is ASUS notebook computer, and its operating system is Windows 10. )

To talk about the keyboard, we might as well start with the first button in the first line of the keyboard. The reason why this button is put in such a conspicuous position is because it is too important.

I wonder when you first used the Esc key? When I first used it, I watched the video. At the moment of full screen, a prompt appears on the screen: press Esc to exit full screen.

I think this is probably the place where the Esc key is used the most. Esc=escape, which means escape. Used alone, this key is used to exit and exit. Combined with the position of ESC key, we might as well regard it as a safety exit. So you can understand the function of this button well. Therefore, people also call the ESC key the exit key.

So what's the use of esc besides exiting the full screen? There are many. In Explorer, cut a file and press esc to cancel it. If you want to cancel the content entered in the search box, press the EESC key; To end the slide show, please press esc ... in short, you just need to remember esc=escape= exit. (esc has no effect on the actual operation and does not have the cancellation function. )

Give another example in detail.

In Word, you may often use the magic thing of format brush, which is really useful when setting the format.

Format brushes can be used for two purposes. One is to click the format brush button, and then you can use the format brush once. The other is to double-click the format brush button, and then you can use the format brush indefinitely until you take the initiative to cancel this function. So, how to cancel the format brush? One is to click the format brush button and the other is to press esc.

Speaking of which, you don't really think I'm just talking about this example, do you? If you really think so, then this reader, you have failed in your study. Confucius said, "If you take a corner instead of a triangle, there is nothing." I ...

Forget it, I'll show you how to draw inferences from one instance to another. Confucius also said, "It's okay to learn and learn from the times." . Have you ever practiced the above example? If there is, you will find that the shape of the mouse will change when you click the format brush, and after using it once, the mouse will return to normal and no longer play the role of the format brush. So we know that the shape of the mouse indicates the operation that the mouse can perform at present, and different mouse shapes can perform different operations, which tells us to pay attention to the changes of the mouse shape at all times.

Conversely, when you see that the mouse has changed, it is probably because you have selected a tool or clicked a button (such as "format brush"). At this time, if you want the mouse to return to normal, just press esc. This technique is very effective when you don't know which button to press (people with a bad memory like me, wrong! )。 Still in the above example, if you forget to click the format brush button, or can't find this button, it is undoubtedly the most convenient to press the esc key to restore the mouse to the normal cursor.

I always thought this was the way to learn things. Don't be greedy, don't be eager for quick success, think more and explore more. Don't cling to the myth of "crash", and don't think about learning any shortcuts. If there is any skill in this world, it can only be that practice makes perfect.

Not much sense, not much nonsense. I seem to talk a lot. Let's talk about a strange usage of the esc key, which is to quickly set the first startup item, which is usually used when installing the system.

The specific operation is as follows: Press esc to start the machine, and a window will appear on the screen. Select the first startup item, and then press enter to confirm.

However, unlike entering the BIOS setting through F2 key, the first startup item set by esc key is only valid for the next startup, while F2 enters the BIOS for setting, which is permanently valid if the setting is not modified. So when installing the system, I suggest using the esc key to set it.

However, it is worth noting that different brands of computers may have different shortcut keys for setting the first startup item. What exactly is it? Find it yourself.

On the same line as the esc key is the f1~ f12 * * *12 special function key. Here, F = function = function.

This 12 function key has different functions in different scenes, which must be noted. It is unrealistic that the functions of these 12 keys have no specific operating environment. I'll just say a few typical ways to use it.

For the key F 1, it seems that I will only use it in one place, that is, when I want to check the help document. Please pay attention to this help document, because the help document that comes with the software (including the operating system) is undoubtedly the most authoritative, professional, comprehensive and reliable guide to use. Generally speaking, help documents are written by developers and then tested by testers, which is highly professional and reliable. So when you read the official, if you encounter any immovable problems, you can try to check the help documents, and you may get unexpected results.

Windows system comes with help documents, to be honest, it's really useful. In the past, whenever I had any questions, the first thing that came to mind was the help document. This is the main bridge between me and the computer. commemorate ...

Sorry, I'm still immersed in the memory of Windows7. In the Windows 10 system I am using now, the help file has disappeared and has been replaced by Cortana. You don't have to press F 1 Just ask Xiao Na.

Although Windows 10 has lost its help document, most software still retains the tradition of viewing help in F 1, so this F 1 key is still very useful.

The typical application of F2 key is to enter the BIOS when the computer is turned on. But friends who are unfamiliar with computers should not easily enter the BIOS. If the settings are incorrect, your computer may not start.

When we enter the BIOS, the most common thing is to set the first startup item when installing the system, such as setting it as a USB flash drive. It should be noted that under the BIOS, the mouse can't be used, only the keyboard can be used, but don't be nervous, there will be operation tips.

If there is any function in the Windows system, I can choose a file and press F2 to rename it, but I don't usually do this. Renaming with the mouse is faster, just select the file and click it again (in fact, it is a slow version of double clicking).

F5 is a refreshing function in most cases, for example, on the desktop, for example, in the browser, it can play a refreshing role.

But please don't think that F5 just refreshes a function. The f function key does not seem to have a single function. So is it still useful?

Take PPT as an example. Ladies and gentlemen, how do you do it when you show the slides? I think many people use the menu command and click Slide Show > Start from scratch/Start from the current slide in the menu bar.

Show from the beginning (F5) (as shown in the figure below), and show from the current slide (Shift+F5). The contents in brackets are the corresponding shortcut keys. So please press F5 to show the slides directly in the future, which will be more professional (laughs).

To be honest, I usually don't want to use F8. Because when I use the F8 key, it usually means that my computer has a blue screen or can't start normally. Similar to the use of F2, press F8 wildly when starting the computer (in fact, it is enough to press it once when the manufacturer's trademark appears on the computer boot screen, but it looks more handsome and laughs).

Then, you will find that your PC is not turned on normally. Read these options carefully, press the arrow keys to select the operation you need to perform, and then press enter to confirm. By the way, I told you the function of the enter key again.

Ctrl = control control. Control key, control, sounds very bullish. However, the so-called "control" naturally requires the object of control. Therefore, just like a puppet master who loses control will become the residue of war, the Ctrl key alone is useless and must work with the object it controls.

Maybe someone is going to fight. No, the Ctrl key can be used alone. For example, in Explorer, I can select multiple targets by holding down the Ctrl key. Obviously, it can be used alone. The author is a big fool!

Heaven and earth conscience, how can I fool everyone? Ctrl key alone is really invalid. As far as the example just now is concerned, it looks like the effect of playing with the Ctrl key, but the real effect is actually the Ctrl key+the left mouse button. No matter what window you are in, if you hold down the Ctrl key, do you think it will agree?

Here are some skills involved in the combination of keyboard and mouse. A common operation of mouse and keyboard is Ctrl+ mouse click to select multiple targets. For the sake of convenience, let's call this combination of keyboard and mouse "shortcut key".

Speaking of shortcut keys, Ctrl is probably the key that constitutes the most shortcut keys. Let's take a look at what are commonly used.

A = select all. Since the question of "choice" is mentioned, let's say Ctrl+A first. Its function is to select all. This shortcut key is available in most windows. At present, as long as it can be selected with the mouse, it can be used to select all.

C = copy copy, so Ctrl+C is copy, why Ctrl+V is paste? I think it's because C and V are close together on the keyboard. Ctrl+C and Ctrl+V are always used in combination. Is my forced explanation good? )

These two keys are too common and famous. Needless to say, if you don't even know these two keys, then you are really a computer white.

F=find search, which is usually used for searching and searching, and is suitable for most windows, such as file explorer, browser, Word, Excel…… ... ...

Revocation, which I think is the greatest shortcut. With it, I'm not afraid of making mistakes at all. Just cancel it. But don't get too carried away. You'd better be careful before the operation. After all, some operations cannot be undone.

O = open open, open the file.

N = New, create a new file.

The above shortcut keys are well-known shortcut keys, which are found in almost all software, but don't think that all software has shortcut keys. Please see below if you don't believe me.

Pay special attention to this shortcut key, because its function is often different in different windows. In the file browser, the operation it performs on the file is to delete; Under the browser, its function is collection; In Word, its function is to open the font dialog box; Under PS, its function is to cancel the constituency ... you can't expect me to list it for you, it's impossible.

Off-topic, readers and friends, I hope that after reading my article, you can draw inferences, but at the same time, I also hope that you can bear in mind the "concrete analysis of specific problems." The two are not contradictory. Don't ask me why. I don't want to talk about dialectics

What you need to pay attention to is, before the operation, ask yourself, what is my current operation environment? What operation am I currently undergoing? Is the mouse in the right position? Is the cursor in the correct state? Otherwise, even if your operation looks good, you still can't achieve the expected effect. Then you will wonder, "There is nothing wrong with my operation. Why is it wrong?"

We talked about a lot of shortcut keys before, and some people want to ask, how can I remember so many shortcut keys? Do you want to remember all the shortcut keys?

I said, friend, you are so stupid. Who told you to really remember all the shortcut keys? Do you remember them? You know, most software has shortcut keys. How can you remember it all? If you insist on remembering, I won't stop you Instead, I will show you the way and teach you how to find all the shortcut keys of a software.

I think many people have seen this interface. The so-called "hotkey" in the picture is actually another name for the shortcut key. Generally speaking, software will have its own shortcut keys, and the keys on the keyboard are limited, so it is inevitable that there will be hot key conflicts. Of course, conflicting hotkeys are often global hotkeys. By the way, this pop-up window also tells us an important message that the hotkey of the software can be modified according to personal habits and special needs.

Now let's go to Software Settings >; Hotkeys > set hotkeys

Yes, you can see all the shortcut keys of this software now. Remember them, Sao nian, I won't accompany you. There seems to be less shortcut keys, and it seems not difficult to remember them all.

So, I will give you more.

Obviously, remembering all the shortcut keys is thankless. First, it's difficult. It's hard for you to really remember all the shortcut keys. Second, it is unnecessary. I can do what you do with hotkeys, just click the mouse on the menu. Besides, it is useless for you to remember many hot keys, because you may not need them at all.

So, what's a better way? My suggestion is that when you are new to a software, you don't need to use hot keys, so you can get familiar with the software faster. When you are familiar with the software interface and have a little experience, you can start using shortcut keys. Besides, at this time, you will know which shortcut keys (hotkeys) are worth remembering and which are more convenient to use the mouse. Generally speaking, I suggest that you remember the shortcut keys of common functions, and some hot keys that are difficult to find in menus are also worth remembering. Other hotkeys, well, as long as you are happy.

This key is one of the few keys marked with a pattern on the keyboard, and its pattern is the Windows logo of Microsoft Windows. It is not difficult to imagine that the function of this button will be system-level. Pressing this button alone will open the Start menu. In addition, it has many very useful shortcut keys.

E = resource administrator. This shortcut key is equivalent to double-clicking the desktop icons "My Computer" (XP)/ "Computer" (Windows7) and "This PC" (Windows10). Don't ask me why I don't have Windows8/8. 1. I haven't used it.

The advantage of this shortcut key is that you don't need to go back to the desktop to find the "this computer" icon. You can open Explorer at any time. The most important thing is to look cool.

L = lock, lock. The function of this key combination is to lock the computer. When you need to leave your computer temporarily, in order to prevent others from using your computer, a very simple and easy way is to press the Windows+L key to lock the screen. If this function really works, you need to set the computer boot password, otherwise you are deceiving yourself by pressing Windows+L.

P = Project, Projection, Set Projection.

The left/right arrow keys can move the current window to the left/right half of the screen, which is very useful when dealing with multiple windows. The up/down arrow keys maximize/minimize the current window respectively.

M = minimum, all windows are minimized. The function of this shortcut key is to minimize all the current windows. Let's talk about the difference between Windows+M and Windows+D. On the surface, the functions of these two shortcut keys are the same. Actually, it's the same. Minimizing all windows will display the desktop. So what's the difference between these two shortcut keys? Yes, after Windows+D displays the desktop, press it again, and the minimized window will be restored. After Windows+M minimizes all windows, press this key combination again and there will be no response. How can I recover? Use Windows? +Shift+M can restore the minimized window.

It is said that people who like to use this shortcut key easily will make their parents have such questions: "I ask you, son, why are you looking at the computer desktop every time I enter your room?"

Yes, seconds back to the desktop is the function of this shortcut key. Explain, D = desktop, desktop. The function of this shortcut key is to "show the desktop", and the effect is the same as clicking the Show Desktop button on the far right of the taskbar. draw

The above picture is obviously a full-screen screenshot. Moreover, I took a screenshot without the help of a third-party screenshot tool or using the screenshot software that comes with the system. How did I do it? Hint: You only need one key on the keyboard. )

Everyone answered enthusiastically. It's a simple question, and there is no reward for getting it right (laughs).
