Keyboard Shortcuts For Uncommenting

Keyboard shortcuts are important tools for any developer seeking to speed up their workflow. In Visual Studio, they deliver a quick and efficient method to uncomment lines of code. For Single Line Comments For Block Comments.

For Block Comments

When you’re performing with numerous lines or block comments, put your cursor anywhere within the commented block and operate the same Ctrl + K, Ctrl + U shortcut.

Console.WriteLine("Line 1");
Console.WriteLine("Line 2");

Console.WriteLine("Line 2");

Similarly, put your cursor anywhere within the block comment before utilizing the shortcut.

After pressing the shortcut:

Console.WriteLine("Hello, World!");  // This line is uncommented

Make sure your cursor is anywhere on the line you expect to uncomment before utilizing the shortcut.

Case Study: Adding Commenting Icons to the Text Edit Toolbar in Visual Studio 2013 Premium

A developer operating Visual Studio 2013 Premium desired to customize the Text Edit Toolbar to include the “Comment Out” and “Uncomment Out” icons around the bookmark icons.

The problem was that when the developer attempted to add these buttons through the Text Editor Toolbar dropdown and then went to Customize > Add Command, the preferred buttons were not available in any of the classifications.

By default, these icons were found on the “Standard” toolbar in Visual Studio 2013 Premium.


The solution was fairly clear. The developer had to:

-Hit the Add/Remove buttons in the toolbar.

-Choose the Customize option.

By obeying these steps, the developer was capable to add the “Comment Out” and “Uncomment Out” icons to the Text Edit Toolbar, completing the customization they were desiring.


Customizing Visual Studio to suit individual coding needs is often a specific technique. In this case, simple navigation to the Customize option through the Add/Remove buttons in the toolbar allowed the developer to add essential features to their Text Edit Toolbar.

This customization enhanced their coding workflow by making the procedure of commenting and uncommenting code more accessible.

Context Menu Options

Console.WriteLine("Line 1");
Console.WriteLine("Line 2");

Simply highlight the lines you like to uncomment, right-click, and select “Uncomment Selection”.
