In the win xp system, the ALT key of the button function is explained.

There are a lot of buttons on the keyboard. I don't know what keys you usually use. Many people will use the Enter key or the space bar, but it is reasonable. The alt key is rarely used. There is an ALT key on the PC key, just like the Shift and Ctrl keys. In general, we use it with other keys, it seems to have little effect. In fact, if you think about it in detail, its role in Windows can be great. If you don't believe it, please see below. I believe that after reading this article, you will definitely see the ALT button on your keyboard.

1. Quickly create shortcuts

Everyone is familiar with shortcuts in Windows. Through shortcuts, we can access the corresponding programs, files or files very quickly. WEB pages, etc., greatly facilitate the user. However, in Windows 2000, if we drag and drop a program or folder to the specified folder, we will not create a shortcut, but copy it (not on the same disk) or move (on the same disk) to the specified folder. So, just right click and select “New”\\“Shortcut", open the folders layer by layer, find the location of these programs or folders to create shortcuts for them, very troublesome. In fact, when you drag a folder, file or program, try to press the ALT key, the cursor will become a link, then release the mouse, you can create a shortcut at the current location. This method also applies to Windows Me and Windows NT.

2, select the contents of the drop-down box

It is very convenient to use the mouse in Windows, but often our mouse will occasionally "strike" & rdquo; this time, in addition to using the keyboard What else can I use? In Windows, there is a lot of content provided by the drop-down box. The corresponding software just selects the default content in the drop-down box. If you want to select other content, you can use it conveniently when you mouse. Click the mouse to click, and when only the disc is pressed, just press the TAB key to switch the focus to the drop-down box, then press ALT+up or down arrow to select.

3, fast switching focus

In Windows dialogs, there are usually multiple items, such as input boxes, drop-down boxes, buttons, option boxes, etc., sometimes with a mouse click It is better to use keyboard selection. If you have a name (C) and a password (P) in a window, you can quickly switch to the name item by pressing ALT+C, and press ALT+P to quickly switch to The password item has the rule that pressing the ALT key does not release, and then pressing the letter behind the object (ie, ALT+ underlined letters to execute the corresponding command or select the corresponding option) is very convenient.

4, input characters not on the keyboard

We can only input characters on the keyboard through the keyboard, in fact, hold down the ALT key, and then press the numeric keypad to indicate the character to be entered. The key of the decimal code value, after the input is completed, the ALT key can be released to input characters that are not on the keyboard.

If the first number typed is “0”, the value will be recognized as the code point or character value in the current input locale. For example, when the current input field is set to “English (United States)" (code page 1252: Windows Latin-1), hold down the ALT key and type "“0163” on the numeric keypad to generate the pound sign £ ( U+00A3). In the current input area is "Russia" (code page 1251: Windows Cyrillic), the same key order will produce the Cyrillic capital letter JE (U+0408).

And if the first digit typed is any number from “1” to "9”, this value will be recognized as the code point in the system OEM code page. The results vary depending on the Windows system locale specified in the "Regional Options" "Control Panel" "Regional Options" For example, if your system locale is &#quo;English (US)" and the code page is 437 (MS-DOS Latin America), just hold down the ALT key and type “163” on the numeric keypad Enter ú (U+00FA, accented lowercase Latin letter U). If the system locale is "Greek" (OEM code page 737 MS-DOS Greece), the same sequence will produce the Greek lowercase letter MU (U+03BC).

In this way, are we giving Windows “ increased & rdquo; another input method?
