#10 Add Guidelines to the Text Editor
3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\
4. Right-click on the Text Editor key and choose New
➝ String Value and
name it “Guides”.
5. Set the value of the guides to
RGB(128, 128, 128) 4, 16.
The first part of the value sets the color of the guidelines using common red,
green, and blue values. 128, 128, and 128 sets the color of the guidelines to
gray. The second numbers specify where the guidelines should appear. In
this example, guidelines will be shown at the 4-space mark as well as the 16-
space mark. You can add up to 13 different guidelines by simply adding
more numeric values separated by commas.
After you have created your registry entry, you will see guidelines in the
marks specified when you launch Visual Studio. Figure 2-21 shows an exam-
ple of the results from the example settings.
Removing these guidelines is simply a matter of deleting the Guides registry
key and restarting Visual Studio.
Guidelines are easy to add and can be very useful when trying to keep your
code organized. Thanks to Sara Ford for posting about this hidden feature
