Troubleshooting flow for Ctrl+Y (Redo) issues in Visual Studio 2019.

Diagnosing and Resolving the Issue

The troubleshooting process involves systematically checking various aspects of your Visual Studio environment. It's often a process of elimination, starting with the simplest and most common fixes before moving to more drastic measures.

1. Verify Keyboard Shortcut Mapping

Open Visual Studio, go to Tools > Options > Environment > Keyboard. In the 'Show commands containing:' field, type Edit.Redo. Ensure that Ctrl+Y is listed as the shortcut for Edit.Redo in the 'Shortcuts for selected command:' box. If not, assign it by placing your cursor in the 'Press shortcut keys:' field, pressing Ctrl+Y, and clicking 'Assign'.

2. Test in Different Contexts

Try using Ctrl+Y in different types of files (e.g., C# code, XML, plain text) and in different projects. This can help determine if the issue is specific to a certain file type or project configuration.

3. Disable Extensions

Many Visual Studio extensions can interfere with default keyboard shortcuts or introduce unexpected behavior. Go to Extensions > Manage Extensions, and disable all installed extensions. Restart Visual Studio and test Ctrl+Y. If it works, re-enable extensions one by one, restarting VS after each, until you identify the culprit. Once found, you can either keep it disabled, look for an update, or report the issue to the extension developer.

4. Reset Visual Studio Settings

Corrupted user settings can sometimes cause odd behavior. You can reset your settings by going to Tools > Import and Export Settings > Reset all settings. Choose to save your current settings if you wish, then proceed with the reset. This will revert all your personalized settings to their default state.

5. Repair Visual Studio Installation

If none of the above steps work, your Visual Studio installation might be corrupted. Open the Visual Studio Installer (search for it in your Start menu), find your installed Visual Studio 2019 edition, and click 'More' > 'Repair'. This process can take some time but often fixes underlying installation issues.

6. Check for Updates

Ensure your Visual Studio 2019 is fully updated. Microsoft frequently releases updates that include bug fixes. Go to Help > Check for Updates to install any pending updates.

Advanced Troubleshooting: Examining the Command Window

For more advanced diagnosis, you can use Visual Studio's Command Window to directly invoke the Redo command and observe its behavior. This can sometimes provide clues if the shortcut itself is the problem, or if the command is simply not executing.

Edit.Redo

Command to manually execute Redo in Visual Studio's Command Window.

To use this, open the Command Window (View > Other Windows > Command Window), type Edit.Redo, and press Enter. If this successfully performs a redo operation, it strongly suggests that the issue lies with your keyboard shortcut mapping or a conflicting extension rather than the Redo command itself.
