Open the main menu and specify a command. How to open the start menu

In this lesson, we will study the Start menu in detail and learn how to customize it for ourselves.

Under your icon account there are menu items. This quick access to folders and settings. By default, a large list of various folders that the user does not need is displayed. Now we will customize the start menu and remove unnecessary items.

Is it possible to work with the Main Menu as a folder?

Selecting this option will display a dialog box that will allow us to perform the following actions. Turn off your computer The moment the message “You can now turn off your computer” is displayed, you will do so knowing that the way to turn it off was the correct one. Install the necessary updates and restart your computer if necessary. Turn off your computer. . If none of the updates require a restart, it is recommended that you restart your device anyway to ensure that all pending updates are installed.

Start Menu Customization

To go to the start menu settings, you need to right-click (RMB) on the start menu icon and select “properties”. Click on the “settings” button.

You will see a list of different options. Now I will show you my start menu settings, which I consider optimal, and explain my choice.

Create a new account local administrator. To create a new administrator account. Then convert the new account to an administrator account. Close your account session and sign in to your new account. If everything is resolved, move your personal data and files to the new account.

If the problem still persists, try deleting the previous administrator account. One of the most common ways to use the Start menu is to open programs installed on your computer. To open a program that appears in the left pane of the Start menu, click it. The program opens and the startup menu closes. If you don't see the program you want to open, click on the All programs option located at the bottom of the left pane. Immediately, the left pane displays a long list of programs in alphabetical order, followed by a list of folders.

As you can see, I have the following items in my menu: Vitaly (account name), computer, games, network, control panel, execute. I removed the remaining points as unnecessary.

In the item “Start Menu Dimensions” I indicated 5 and 5. This is necessary so that it is not very elongated to the top. You can specify more if required.

If you click on one of the program icons, the program will launch and the start menu will close. What's inside the folders? For example, if you click Accessories, a list of programs stored in that folder will appear. Click any program to open it. To return to the programs you see when you first open the Start menu, click the Back button located at the bottom of the menu.

If you never know what a program does, move the pointer over its icon or name. Over time, you will notice that the lists of programs in the Start menu change, this is due to two reasons; firstly, when new programs are installed, they are added to the All Programs list, secondly, the Start menu determines which programs or applications are used most often and places them in the left pane so that they can access them faster .

I advise you to definitely leave the same menu items as I have, we will need them for further development of the computer, and if you need to add your own.

In this lesson, we took a closer look at the Start menu and learned how to customize it. Customizing the Start menu makes working on your computer easier and more convenient.

This concludes the lesson. We write all questions in the comments.

The search box is a very powerful feature for searching items on your computer, the exact location of the files does not matter as the search box performs its function in all the folders of your personal folder. It will also search email messages, saved instant messages, appointments, and contacts.

To use the search box, open the start menu and start typing, there is no need to click inside the box as it is enabled by default and as you type they will appear above the search box in the left pane of the start menu, results that match the options written. Program, file, folder, image, audio, video, application may appear in the results if.

The main menu of the Windows operating system implements the main method of launching installed application programs and system controls. To access this menu, a graphical interface element is placed on the taskbar, which is usually called the “Start” button, although in latest versions The OS no longer has such an inscription. In addition to accessing programs, the main menu is used to turn off the computer and perform various search operations in the system.

Its title word matches or begins with the search term. - The text of the file's contents—for example, the text of a word processing document—matches or begins with the search term. - Any word of the file - for example, author, matches the search query or begins with it.

Click on any search result to open it. Or click the Clear button to clear the results and return to the list of main programs. You can also click the Show All Results button to display the search results in a folder with more advanced options; Or search the Internet to open your web browser and search for a term, file, or application on the Internet. If your search doesn't return any results, you can click Search Everywhere to search the entire team.

Purpose Matlab

The Matlab system (Matrix Laboratory) was developed by MathWork . It's powerful computing system, designed to solve a wide range of mathematical, engineering and economic problems.

Working in the Matlab(ML) environment, a user, even if he is not a programmer, can easily and quickly solve computational problems in various fields of science and technology (linear algebra, control theory, signal processing, etc.). A simple command environment allows you to enter expressions in a form that closely resembles natural mathematical notation.

The system is most focused on performing engineering calculations. The mathematical apparatus is optimized for calculations performed with matrices and complex numbers. Matlab contains many built-in functions required by the engineer and scientist to perform complex numerical calculations as well as behavioral modeling technical systems and physical processes. The powerful graphical system of Matlab allows you to visualize the data representation, which makes graphical analysis of the results possible. All functionality combined with a convenient user interface.

The big advantage of the system is its openness and expandability. Programs can be written in it for repeated use. The user can not only use existing functions, but also create their own specialized functions. The package allows you to work with programs written in Fortran C languages. Most specialized functions are stored as text files with extension m(m-files). Files can be created in the Matlab environment editor or in an external editor that is encoding compatible with the built-in editor. User created m- the files can be used in the same way as Matlab's built-in functions.

In addition to working with programs (functions), calculations can be performed in “calculator” mode, i.e. get the result immediately after entering the next command. To solve special problems using ML, packages with additional functions, which are called Toolboxes.

It is possible to integrate the ML system with Microsoft Word and Microsoft Excel.

Matlab 6.5 interface

After starting the Matlab program, the main window is displayed working environment ML, which is called the “desktop” (Fig. 1).

This window contains:

· title line;

· main menu bar containing menu items File(File), Edit(Editing), View(View), Web, Window
(Window), Help(Reference).

· a toolbar with buttons that allow you to perform some of the most common operations, which can also be selected through the menu. There is a window nearby Current Directory, which allows you to set the current folder;

· three internal windows:

Ø on the right is the largest and most important window - Command Window(command window), which displays user input, commands and their execution results, as well as error messages;

Ø top left window with tabs Workspace(workspace), allowing access to the contents of the workspace, and Launch Pad, used to view the contents of a folder M.L.(for example, to view demos or call help);

Ø bottom left window with tabs Command History(command history), intended for viewing and re-calling previously entered commands, and a window Current Directory(current folder), used to set the current directory;

· status bar where system messages are displayed.

There are two buttons in the right corner of each window: X – close; – unpin from the desktop. To return to the previous state, you must select the menu items: View, Desktop Layout, Default.

All variables used in the current work session are stored in the computer memory in an area called Workspace(workspace). A complete list of specified variables is displayed in the window Workspace. Contained here full list variables and their sizes, but not the values ​​of the variables. Double clicking on a variable name opens a window Array
Editor, which can be used for editing individual elements vectors and matrices.

You can adjust the size of windows using the mouse.

Basic commands of the ML main menu

Working with menus in ML is similar to working with menus Microsoft programs Office. Many menu items have hotkeys for quickly calling commands (you can see them to the right of the command, for example, Copy→Ctrl+C etc.).

Let's look at the composition and purpose of some menu commands.

Working with files. Menu item File contains the following commands (Fig. 2):

New – m-file– allows you to create a new m-file in the ML editor;

Open– allows you to open an existing m-file;

Set Path– allows you to set a path indicating the location m-files;

Preferences– allows you to display a dialog box in which you can configure various system parameters.

In the menu item window File The names of the last four files accessed by the user are displayed.

All files that will be created by the student in ML must be stored in a designated folder where saving files is allowed: on the C: drive (C:\USERS\<папка>) or on the server (N:\<папка>). It is always possible to set the desired directory as the current one. This can be done using the menu item File, Set Path or in the window Current Directory(Current directory).

Team Exit allows you to log out.

Editing. Menu item Edit contains traditional commands: Undo And Redo(cancel the last action and refuse to cancel, respectively), Cut(cut out fragment) Copy(copy), Paste(insert), Delete(delete), Select All(select all).

Using commands Clear Command Window, Clear Command History, Clear Workspace, you can clear the contents of the command window, command history window, and workspace, respectively.

Desktop configuration management. Menu item View(Fig. 3) allows you to manage the desktop configuration if necessary (the presence of windows can be controlled by checking or unchecking the boxes next to the selected menu commands).

Working with windows. Menu item Window used to work with system windows. This displays commands that correspond to the windows and programs that are currently open. Selecting one of these commands allows you to make the desired window or program code active in the editor m-files.

Menu item Help provides access to help system programs Matlab.

Command Window. This window is for entering numbers, variables, expressions and commands. The results and error messages are also displayed here. The readiness of the system for input is indicated by the >> sign, which is located in the text field of the command window (on the command line). To execute the entered command, press the key . As long as it is not pressed, the entered expression can be edited or deleted. Viewing the contents of the window can be done using scroll bars, as well as keys < PgUp > , < PgDown > , < Ctrl+Home > , < Ctrl+End > , < Home > , < End >.

The control keys and ¯ in ML have a completely different purpose than in text editors. Using these keys allows you to display previously entered commands and expressions on the command line so that you can reuse them. This is possible because all executed commands are stored in a special memory area. To erase the contents of the command window, just type and execute the command clc.

Workspace. In ML, all variables used in the current work session are stored in an area called the workspace or workspace. A complete list of used variables is displayed in the window Workspace where you can see a list of current variables and their sizes. This information is presented in the form of a table consisting of the following columns: Name– the name of the variable is indicated, Size– the size of the variable is displayed, Bytes – displays the amount of allocated memory , Class– variable type.

Window Workspace has a toolbar that includes commands for opening data files, creating, saving and deleting variables. If you double-click on the line corresponding to a variable, information about it will be displayed in the window Array Editor.

Team history. Command History Window– the date and time of the ML session are displayed here, and also contains a list of commands entered during the current session. They can be re-executed by double-clicking on the command. You can execute several commands in this window in a row. To do this, select commands using the mouse while holding down the key and then press . If necessary commands are not located in a row, then they must be selected by holding down the key . You can also use the ↓ arrow keys to reuse commands by placing those commands on the command line. When you right-click on any command, this window displays a context menu containing commands for copying the selected command to the clipboard, deleting it, creating m-file, etc.

Main menu- one of the main system controls Windows XP. Main menu opens with a click of a button Start. By using Main menu you can run all programs installed under or registered with the operating system, open the latest documents you worked with, gain access to all operating system configuration tools, as well as access to search and help systems Windows XP.

To the structure Main menu includes two sections - required And arbitrary.

Mandatory section of the Main Menu.

The required section of the Main Menu includes the following items.

Programs– provides access to a hierarchical structure containing pointers to launch applications installed on your computer. Pointers are combined into categories.
