Mastering VS Code shortcut keys can significantly improve coding efficiency. 1. File and window operation: Ctrl P opens the file, Ctrl Tab switches the file, Ctrl \ or 1/2/3 switches the column, Ctrl W closes the file, Ctrl Shift W closes the window; 2. Editing and selection skills: Alt left mouse button realizes multi-cursor editing, Shift Alt ↓/↑ Copy rows, Ctrl L selects the entire line, Ctrl D selects the same keyword, Ctrl / comment code; 3. Search and navigation: Ctrl F search, Ctrl H replaces, Ctrl Shift F global search, F12 jump definition, Ctrl Shift O jump symbol. It is recommended to print a list of shortcut keys next to the monitor or save the desktop to gradually form muscle memory and greatly improve development efficiency.

If you want to quickly improve coding efficiency, a compiled VS Code shortcut PDF is really useful. Many people know some commonly used shortcut keys when using VS Code, but they do not have the system mastery, resulting in the failure to fully utilize the efficiency. In fact, just print out the most commonly used shortcut keys and paste them next to the monitor, or save them to the desktop for review at any time, and you can quickly form muscle memory.

The following parts are the most worthy directions I usually sort out, and are also the functional categories that most developers use frequently:

File and window operations

This part mainly involves opening, switching and closing files or windows, and is a basic skill that needs to be used every day.

• Ctrl P : Quickly open the file (you can jump out within a few seconds after entering the file name)
• Ctrl Tab : Switch between recently opened files
• Ctrl \ or Ctrl 1/2/3 : Switch the editor columns in order, suitable for multi-window development
• Ctrl W : Close the current file, only one when multiple windows are closed
• Ctrl Shift W : Close the entire VS Code window directly

It is recommended that you use shortcut keys instead of clicking "X" on the mouse to close the tab, so that the rhythm will be smoother. Especially when you open more than a dozen files at the same time, shortcut keys can help you save a lot of time.

Editing and selection skills

VS Code has very powerful editing functions. Many things that seem to require plug-ins to complete, but in fact they only need to combine a few shortcut keys.

• Alt 鼠標(biāo)左鍵or Alt Shift 方向鍵: Multi-cursor editing, especially suitable for batch editing and changing the volume name or repeating structure
• Shift Alt ↓/↑ : Copy the current line to move up and down, much faster than manual Ctrl C/V
• Ctrl L : Select the current entire line, press it again to expand the next line
• Ctrl D : Continuous pressing can gradually select the same keyword, which is suitable for modifying multiple variables of the same name at one time.
• Ctrl / : Comment the current line or select the code block, supports multiple languages

After you are proficient in these operations, you will find that writing code is like "commanding", rather than typing word by word.

Search and Navigation

The search function is one of the most powerful parts of VS Code, especially in large projects to find content, jump definitions, etc.

• Ctrl F : Search in the current file
• Ctrl H : Replace the current file content
• Ctrl Shift F : Global search for the entire project
• F12 : Jump to the variable or function definition (provided that language service supports)
• Ctrl Shift O : Quickly jump to a symbol (such as function name, class name)

If you often maintain other people's code or read the source code of open source projects, you must be familiar with this set of shortcut keys. With multiple cursors and selection techniques, changing the code is like "precision strike".

Basically that's it. At first, you may feel that you can't remember it, but as long as you use it a few times a day, you will be able to use it within a week. You can go online to find a PDF of VS Code shortcut keys and print it out and paste it, or make a simple version of the memo and put it on the desktop. The key point is not to remember everything, but to know what you can use and to quickly look it out and check it out when you encounter problems.
