Written in front:

I think everyone is familiar with things like keyboards. Because it is so commonplace, we don’t seem to have a good understanding of the keyboard. So, I think, let’s get to know the keyboard better. (The PC used in the example in this article is an ASUS laptop, and the operating system is Windows 10)

Talking about the keyboard, we might as well start with the first key on the first row of the keyboard. The reason why this key is It is placed in such a conspicuous position because this button is too important.

I don’t know when you first used the Esc key. The first time I used it was when watching a video. At the moment of full screen, a line of prompts appeared on the screen: Press the Esc key to exit full screen.

I think this is probably where the Esc key is used the most. esc=escape, meaning to escape. Used alone, the function of this key is to escape and exit. Combined with the location of the ESC key, we might as well regard it as a safe exit. This way you can better understand the function of this button. Therefore, people also call the ESC key the escape key.

So besides exiting full screen, what other uses does the esc key have? There are too many. In the resource manager, if you cut a file and want to cancel, press the esc key; if you want to cancel the content entered in the search box, press the EESC key; if you want to end the slide show, press the esc key... ...Anyway, you just need to remember, esc=escape=exit. (esc has no effect on the actual operation that produces the effect, and it does not have the undo function.)

Let’s give another more detailed example.

In Word, you may often use the magical tool of format brush. This tool is really easy to use when setting formats.

There are two ways to use Format Painter. One is to click the Format Painter button, and then you can use Format Painter once. The other is to double-click the format brush button, and then you can use the format brush unlimited times until you actively cancel this function. So, how to cancel Format Paint? The first is to click the format painter button, and the second is to press the esc key.

Having said that, you don’t really think I’m just talking about this example, do you? If you really think so, then this judge, you have failed in learning. Confucius said: "If you take one example and don't use three examples to reflect it, it will be useless." I...

Forget it, let's demonstrate how to draw inferences from one example. Confucius also said: "Learning and practicing it from time to time are not the same thing." Have you ever practiced the above example? If so, you will find that when you click the Format Painter, the shape of the mouse will change. After using it once, the mouse returns to normal and no longer exerts the effect of the Format Painter. So we know that the shape of the mouse indicates the operations that the current mouse can perform. Different mouse shapes have different operations. This tells us that we should always pay attention to changes in the mouse shape.

On the other hand, when you see the shape of the mouse changing, it is probably because you selected a certain tool or clicked a button (such as "Format Painter"). At this time, if you If you want the mouse to return to normal, press the esc key. This trick works great when you don’t know what button you clicked (for people like me who have a bad memory, err!). Still using the above example, if you forget that you clicked the format brush button, or you can't find the button, and you want to restore the mouse to the normal cursor, pressing the esc key is undoubtedly the easiest thing to do.

I have always felt that this is how we should learn things. Don't be greedy for too much, don't be quick, but think more and explore more. Don't be obsessed with the myth of "quick success", and don't think about taking shortcuts to learn skills. If there is any skill in this world, it is that practice makes perfect.

Don’t talk too much about the truth and talk less nonsense. (I seem to have a lot of nonsense) Let’s talk about a very peculiar use of the esc key, which is to quickly set the first startup item. This is usually used when installing the system.

The specific operation is as follows. Press the esc key when booting. A window will appear on the screen. Select the first startup item and press the enter key to confirm.

However, unlike entering the BIOS settings through the F2 key, the first startup item set by the esc key is only valid for the next startup. If F2 enters the BIOS for settings, if you do not modify the settings, it will be permanent. Effective. Therefore, when installing the system, I recommend setting it through the esc key.

However, it is worth noting that different brands of computers may have different shortcut keys for setting the first startup item. Check it out yourself.

On the same row as the esc key are the 12 special function keys F1~F12***. Here, F=function=function.

These 12 function keys have different functions in different scenarios. This must be noted. It is unrealistic to talk about the functions of these 12 keys without the specific operating environment. I will only talk about a few typical usage methods.

For the F1 key, I seem to only use it in one place, and that is when I want to view the help documentation. Please be sure to 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 usage guide. Generally speaking, help documents are written by developers and then tested by testers. They are highly professional and very reliable. Therefore, as readers, if you encounter any problem that it does not work, you can try to check the help document, and you may get unexpected gains.

The help document that comes with the Windows system is really easy to use. In the past, whenever I had any questions, the first thing that came to my mind was the help document. That is the main bridge between me and the PC. I still remember...

Sorry, I am still immersed in the memory of Windows 7. In the Windows 10 system I am currently using, the help document has disappeared. Instead, it’s Cortana. You don’t need to press F1, just ask Cortana.

Although the help document that comes with Windows 10 is gone, most software still retains the tradition of viewing help with F1, so the F1 key is still very useful.

A typical application of the F2 key is to enter the BIOS when the PC is turned on. However, friends who are not familiar with computers should not enter the BIOS easily. If the settings are improper, your computer may not start up.

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

If it has any effect in the Windows system, I can think of selecting the file and pressing F2 to rename it, but I generally don’t do this. To rename, it is faster to use the mouse and select the file. Just click again (actually a slower version of double-clicking).

F5 is a refresh function in most cases. For example, on the desktop or in a browser, it can refresh.

But please don’t think that F5 just refreshes a function. The F function key does not seem to have only a single function. So what other uses does it have?

Let’s take PPT as an example. Guys, how do you do it when presenting slides? I think many people use menu commands, click Slide Show on the menu bar > Start from the beginning/Start from the current slide.

Start the show from the beginning (F5) (as shown in the figure below), start the show from the current slide (Shift+F5), the content in brackets is the corresponding shortcut key. Therefore, if you are presenting a slide show in the future, please be sure to press the F5 key to show it directly, which will look more professional (laughs).

To be honest, I generally don’t want to use the F8 key. Because when I use the F8 key, it often means that my computer has a blue screen or cannot start normally. Similar to the usage of F2, when booting up, press F8 wildly (in fact, just press it once when the manufacturer's logo appears on the computer startup screen, but it looks more handsome when you press it wildly, lol).

Then, you will find that your PC does not boot normally. Read the options carefully, press the arrow keys to select the operation you need to perform, and press the enter key to confirm.

(I will tell you the function of the enter key again by the way)

Ctrl=Control control. Control keys, control, sound pretty cool. However, the so-called "control" naturally has to have something to control. Therefore, just like a puppet master will become a scumbag once he loses the puppet he controls, the Ctrl key It has no effect when used alone. It must be used together with the object it controls to be effective.

Maybe someone is going to argue, no, the Ctrl key can be used alone. For example, in the resource manager, I can select multiple targets by holding down the Ctrl key. It can be used alone. Author, you are a big liar!

In all conscience, how could I deceive everyone? It is true that the Ctrl key has no effect if used alone. Taking the example just now, it seems that the effect of the Ctrl key is exerted, 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 respond?

This involves some techniques for using the keyboard and mouse together. A common operation using both keyboard and mouse is the Ctrl key + mouse click to select multiple targets. For convenience, we also call this kind of operation that combines keyboard and mouse as "shortcut keys".

Speaking of shortcut keys, the Ctrl key is probably the key that makes up the most shortcut keys. Let’s take a look at some of the commonly used ones.

A=all selects all. Since we mentioned the issue of "selecting" before, let's talk about Ctrl+A first. Its function is to select all. This shortcut key is available in most windows. For now, as long as it can be used You can use this shortcut key to select all places selected by the mouse

C=copy, so Ctrl+C means copying, why does Ctrl+V mean paste? I think it's probably because C and V are close to each other on the keyboard. Ctrl+C, Ctrl+V are always used in combination. (Is my forced explanation very 6?)

These two keys are too commonly used and famous. Without going into details, if you don’t even know these two keys, then you really don’t know them. I am a computer novice.

F=find, this set of key combinations is usually used for search and find, and is applicable in most windows, such as file explorer, browser, Word, Excel...

Undo, this is the greatest shortcut key in my opinion. With it, you are not afraid of making mistakes at all. At worst, you can just undo. However, don’t get too carried away. It’s better to be careful before performing an 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, and they are used in almost all software It is universal, but don’t think that the shortcut keys are universal in all software. If you don’t believe it, please read below.

Pay special attention when using this shortcut key, because its functions are often different in different windows. Under the file explorer, its function is to delete the file; under the browser, its function is to collect; under Word, its function is to open the font dialog box; under PS, its function is to cancel Constituencies...don’t expect me to list them all for you. This is impossible.

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

What everyone needs to pay attention to is that before performing a certain operation, ask yourself, what is my current operating environment? What am I currently operating on? Is the mouse in the right position? Is the cursor in the correct state? Otherwise, even if your operation seems to be fine, you still cannot achieve the effect you want, and you will still wonder, "My operation was fine, why is it wrong?"

We have already mentioned this before. I have talked about a lot of shortcut keys. Someone may ask, how can I remember there are so many shortcut keys? Do I need to memorize all the shortcut keys?

I said, friend, you are stupid. Who asked you to really remember all the shortcut keys? Do you remember them all? You know, most software has shortcut keys, how can you remember them all? If you insist on remembering it, then I won't stop you. Instead, I will give you a clear path and teach you how to find all the shortcut keys for a software.

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

Now we enter the software settings>Hotkeys>Set hotkeys

Yes, you can now see all the shortcut keys of this software, go and remember it, Saonian, I won't accompany you anymore. It seems that there are relatively few shortcut keys, and it seems that it is not difficult to remember them all.

So, I’m going to get a lot of them for you.

Obviously, memorizing all the shortcut keys is a thankless task. First, it is difficult, and it is difficult for you to really remember all the shortcut keys. Second, it is not necessary. The operations you perform through hotkeys can be completed by clicking the mouse through the menu. Moreover, it is useless for you to remember many hotkeys because you may not use them at all.

So, what is a better approach? My suggestion is that when you first come into contact with a software, you don’t need to use hotkeys and use menus more. This can help you become familiar with the software faster. When you are more familiar with the software interface and have some experience, you can You can start using shortcut keys, and at this time you will know which shortcut keys (hot keys) are worth remembering, and which ones are more convenient to use the mouse. Generally speaking, I recommend that you memorize the shortcut keys for commonly used functions, and some hotkeys that are difficult to find in the menu are also worth remembering. As for the other hot keys, well, as long as you are happy.

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

E=explorer, resource manager. The function of this shortcut key is equivalent to double-clicking the desktop icon "My Computer" (XP)/"Computer" (Windows 7) "This PC" (Windows 10). (Don’t ask me why I don’t have Windows 8/8.1, 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 PC” icon. You can open the resource manager at any time. . Most importantly, it looks cool.

L=lock, lock. The function of this key combination is to lock the computer. When you need to leave the computer temporarily, in order to prevent others from using your computer, a very simple and trouble-free method is to press the Windows + L key to lock the screen. For this function to really work, you need to set a computer power-on password. Otherwise, you will be fooling yourself if you press 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. When dealing with multiple windows, this method Very useful. The up/down arrow keys maximize/minimize the current window respectively.

M=minimum, minimize all windows. The function of this shortcut key is to minimize all current windows.

Let’s talk about the difference between Windows+M and Windows+D. On the surface, these two shortcut keys do the same thing. In fact, it is indeed the same. After minimizing all windows, the desktop will be displayed. So is there any difference between these two shortcut keys? Yes, after Windows+D displays the desktop, pressing it again will restore the window that was minimized just now. After minimizing all windows with Windows+M, there is no response when pressing this key combination again. How can I restore it? Use Windows? + Shift + M to restore the window you just minimized.

I heard that people who like to use this shortcut key tend to make parents have questions like this: "Son, I want to ask you something, why do you look at the computer desktop every time I enter your room?"< /p>

Yes, returning to the desktop in seconds is the function of this shortcut key. Explain, D=desktop, desktop. The function of this shortcut key is to "Show Desktop", and its effect is the same as clicking the Show Desktop button on the far right of the taskbar. As shown in the picture

The picture above is obviously a full-screen screenshot. Moreover, I took the picture without using a third-party screenshot tool or the system’s own screenshot software. How do I do this? Did it? (Tip: All it takes is one key on the keyboard.)

Please answer it enthusiastically. It is a very simple question, and there is no reward for correct answers (laughs).
