In VS Code, there are several shortcuts for selecting multiple lines of content. The key is to select the appropriate method according to the scene. The first is to use the left button of the Alt mouse to add multiple cursors, which is suitable for alignment and modification of multiple contents; the second is the shortcut key Ctrl Alt ↑ / ↓ to add upper and lower cursors, which is suitable for quick editing of multiple rows; the third is to use Ctrl D to select the same phrases one by one, which is suitable for modifying the recurring variable names or function names; the fourth is to select a column in batches: Shift Alt Drag the mouse to handle tabular text or fixed format data. Flexible switching of these methods in different scenarios can greatly improve the efficiency of code writing.
In VS Code, there are actually several shortcuts to select multiple lines of content. The key is to select the appropriate method according to the scene. Here are a few common techniques that can double your efficiency when editing code.

Use the Alt left mouse button to add multiple cursors
This is the most intuitive way to edit multiple lines. Hold down the Alt
key ( Option
on Mac), and click on multiple places you want to insert the cursor with your mouse, and each click will add a cursor. After entering the text, all cursor locations will be edited synchronously.
- Suitable for alignment and modification of multiple contents, such as prefixing or suffixing several rows of variables
- You can drag the mouse to select an area vertically to achieve batch editing of the entire text
This method is simple and direct, but requires manual positioning of each row. If you face dozens of rows or even hundreds of rows, it will not be efficient enough.

Shortcut key Ctrl Alt ↑ / ↓ Add upper and lower cursors
If you already have a cursor in one position, you can use Ctrl Alt ↑
or ↓
to add an extra cursor up or down to the previous or next line.
- Press to add one line of cursor at a time, and you can select many lines by pressing continuously.
- Suitable for quick editing of multiple lines of continuous lines, such as commenting out several lines of code at the same time
Note: This method will not automatically skip empty lines or match content, and can only add cursors in order.

Use Ctrl D to select the same phrases one by one
When you want to modify multiple identical words at the same time, select the word first, and then press Ctrl D
multiple times. VS Code will select the next same word in turn, and add a cursor to each time.
- Suitable for modifying repeated variable names, function names, etc.
- If no word is needed in the middle, you can use
Ctrl K, Ctrl D
to skip the current item
This function is very practical, especially when refactoring the code, which can help you quickly locate and modify multiple targets.
Select a column in batches: Shift Alt Drag the mouse
If you want to select a vertical area (such as a column of data in a log file), you can use Shift Alt
and drag the mouse to select the rectangle.
- It also supports keyboard direction key movement selection range
- Commonly used to process table text or fixed format data
This method is especially suitable for extracting specific column content from a bunch of text, or deleting a column at once.
Basically these are the common methods. You can switch flexibly in different scenarios, and the speed of writing code after mastering it will be much faster.

There are three ways to change the default terminal in VSCode: setting through a graphical interface, editing settings.json file, and temporary switching. First, open the settings interface and search for "terminalintegratedshell" and select the terminal path of the corresponding system; secondly, advanced users can edit settings.json to add "terminal.integrated.shell.windows" or "terminal.integrated.shell.osx" fields and escape the path correctly; finally, you can enter "Terminal:SelectD through the command panel

1. Confirm whether the command is installed 2. Check the terminal shell type 3. Update the PATH environment variable 4. Restart VSCode or terminal. When you enter a command in the VSCode terminal, you should first check whether the command has been installed correctly and can be verified through other terminals of the system; secondly, confirm the shell type used by VSCode and check its configuration file; then make sure that the path where the command is located has been added to the PATH environment variable, and manually add and reload the configuration if necessary; finally close and reopen the terminal or restart VSCode to make the changes take effect.

When the "Timedoutwaitingforthedebuggertoattach" issue occurs, it is usually because the connection is not established correctly in the debugging process. 1. Check whether the launch.json configuration is correct, ensure that the request type is launch or attach and there is no spelling error; 2. Confirm whether the debugger is waiting for the debugger to connect, and add debugpy.wait_for_attach() and other mechanisms; 3. Check whether the port is occupied or firewall restricted, and replace the port or close the occupied process if necessary; 4. Confirm that the port mapping and access permissions are configured correctly in a remote or container environment; 5. Update VSCode, plug-in and debug library versions to solve potential

VSCode workspace is a .code-workspace file that saves project-specific configurations. 1. It supports multi-root directory, debug configuration, shortcut key settings and extension recommendations, and is suitable for managing different needs of multiple projects. 2. The main scenarios include multi-project collaboration, customized development environment and team sharing configuration. 3. The creation method is to save the configuration through the menu File>SaveWorkspaceAs.... 4. Notes include distinguishing between .code-workspace and .vscode/settings.json, using relative paths, and avoiding storing sensitive information.

There are two ways to set environment variables for VSCode terminals on Linux: one is to use the terminal.integrated.env.linux configuration item to define variables that are only used by VSCode; the other is to modify the shell configuration file to take effect globally. 1. In VSCode, add variables such as "MY_VAR":"my_value" by setting the terminal.integrated.env.linux field. This method only affects the VSCode terminal; 2. Modify shell configuration files such as ~/.bashrc or ~/.zshrc and add exportMY

To set debug environment variables in VSCode, you need to use the "environment" array configuration in the launch.json file. The specific steps are as follows: 1. Add "environment" array to the debugging configuration of launch.json, and define variables in key-value pairs, such as API_ENDPOINT and DEBUG_MODE; 2. You can load variables through .env files to improve management efficiency, and use envFile to specify file paths in launch.json; 3. If you need to overwrite the system or terminal variables, you can directly redefine them in launch.json; 4. Note that

To access the settings.json file of VSCode, you can directly open it through the command panel (Ctrl Shift P or Cmd Shift P). The default storage location of the file varies according to the operating system. Windows is in %APPDATA%\Code\User\settings.json, macOS is in $HOME/Library/ApplicationSupport/Code/User/settings.json, Linux is in $HOME/.config/Code/User/

Enable Git automatic pull (autofetch) in VSCode needs to be implemented by configuring Git and VSCode settings. 1. Configure Git to remotely get all branches: execute gitconfig --globalremote.origin.fetch "refs/heads/*:refs/remotes/origin/*". 2. Turn on automatic fetch in VSCode: Set "git.autofetch":true to execute gitfetch regularly. 3. Optional installation extensions such as GitLens or AutoFetchforGit are more powerful
