This article explains how to compare files, highlighting VS Code’s built-in features and how they enhance productivity, especially when making critical decisions with clear comparisons on COMPARE.EDU.VN.
1. What Are The Default Keyboard Shortcuts In Visual Studio Code?
Visual Studio Code provides a rich set of default keyboard shortcuts that significantly enhance productivity by allowing developers to keep their hands on the keyboard while coding. Customization is also supported, enabling users to tailor shortcuts to their specific needs. These shortcuts include functionalities like multiple selections, shrinking/expanding selections, column selection, and more, making code editing faster and more efficient.
2. How Can You Make Multiple Selections For Simultaneous Edits In Visual Studio Code?
VS Code supports multiple cursors, enabling simultaneous edits. Add secondary cursors with Alt+Click. Use Ctrl+Alt+Down or Ctrl+Alt+Up (or ⌥⌘↓ and ⌥⌘↑ on macOS) to insert cursors below or above. Ctrl+D (or ⌘D on macOS) selects the word at the cursor or the next occurrence of the current selection. This is an efficient way to perform the same edit in multiple places at once.
3. How Do You Use The Multi-Cursor Modifier Setting In VS Code?
To change the modifier key for multiple cursors (default is Alt+Click), adjust the editor.multiCursorModifier setting. Options include ctrlCmd (Ctrl on Windows, Cmd on macOS) and alt. You can also use the Selection > Switch to Ctrl+Click for Multi-Cursor or Selection > Switch to Alt+Click for Multi-Cursor menu items to toggle this setting. This customization ensures compatibility with other editors’ conventions.
4. How Can You Quickly Shrink Or Expand A Selection In VS Code?
Quickly shrink or expand the current selection using Shift+Alt+Left (or ⌃⇧⌘← on macOS) and Shift+Alt+Right (or ⌃⇧⌘→ on macOS). This feature is useful for precisely selecting code blocks.
5. How Do You Perform Column (Box) Selection In Visual Studio Code?
To perform column selection, place the cursor in one corner and hold Shift+Alt while dragging to the opposite corner. Alternatively, use keyboard shortcuts like Shift+Down, Shift+Up, Shift+Left, and Shift+Right. This mode can also be enabled globally via the Selection > Column Selection Mode menu item or by toggling the Status bar indicator. Column selection is useful for editing tabular data or aligning code.
6. How Does Auto Save Work In VS Code, And How Can You Customize It?
By default, VS Code requires manual saving (Ctrl+S or ⌘S). Enable Auto Save via File > Auto Save. Customize Auto Save settings in User or Workspace settings using options like files.autoSave to save after a delay or when focus leaves the editor. You can also disable Auto Save for specific languages by adding language-specific rules in the settings.json file. For instance, to disable Auto Save for LaTeX files:
<span><span> "[latex]"</span><span>: {</span></span> <span><span> "files.autoSave"</span><span>: </span><span>"off"</span><span>,</span></span> <span><span> },</span></span> Auto Save ensures you never lose your work, and customization provides flexibility for different project needs.
7. What Is Hot Exit In VS Code, And How Can You Configure It?
Hot Exit allows VS Code to remember unsaved changes when you exit. Configure it via the files.hotExit setting with options like "off", "onExit", and "onExitAndWindowClose". Backups are stored in specific folders depending on the operating system:
- Windows:
%APPDATA%CodeBackups - macOS:
$HOME/Library/Application Support/Code/Backups - Linux:
$HOME/.config/Code/Backups
Hot Exit ensures that your work is preserved across sessions.
8. How Can You Find And Replace Text In The Currently Opened File In VS Code?
Press Ctrl+F (or ⌘F on macOS) to open the Find Widget. Use Enter and Shift+Enter to navigate results. VS Code saves the history of find and replace queries, configurable with the editor.find.history and editor.find.replaceHistory settings. Setting the value to never disables saving the history. The Find Widget can also automatically populate the selected text using the editor.find.seedSearchStringFromSelection setting.
9. How Do You Use The “Find In Selection” Feature In VS Code?
Enable “Find In Selection” by clicking the hamburger icon on the Find Widget. The find operations will then run on the selected text only. To make this the default behavior, set editor.find.autoFindInSelection to always or multiline setting.
10. What Are The Advanced Find And Replace Options Available In VS Code?
The Find Widget includes advanced search options like “Match Case”, “Match Whole Word”, and “Regular Expression”. The replace input box supports case preserving, enabled by clicking the Preserve Case (AB) button. Multiline support is also available by pasting text into the input boxes and using Ctrl+Enter to insert new lines. The Find Widget can be resized by dragging the left sash.
11. How Can You Search Across Files In VS Code?
Press Ctrl+Shift+F (or ⇧⌘F on macOS) to search over all files in the currently opened folder. Search results are grouped by file, with previews of the hits. Click on a hit to view it in the editor. Advanced search options, including patterns to include or exclude, are available by clicking the ellipsis (Toggle Search Details). You can also use glob pattern syntax. From the Explorer, you can right-click on a folder and select Find in Folder to search inside a folder only.
