How can we save all files in (VSCode) like we do in Visual Studio

⌥+⌘+S // macOS

Ctrl+K S // Windows

Ctrl+Alt+S // Linux

It doesn't look like VS Code has a built-in single-press keyboard shortcut to save all open files on Windows.

The simplest way would be to use the menu accelerators: ALT+F, followed by ALT+L.

Alternatively, you can change the key binding by editing the keyboard preferences:

Add the binding to the right half of the screen, then restart VS Code:

// Place your key bindings in this file to overwrite the defaults
[
    { 
      "key": "ctrl+shift+s", 
      "command": "workbench.action.files.saveAll" 
    }
]
