# Commenting out code

You can comment out one or more lines of code. The leading characters `//` are added to the beginning of each line.

Tip: The characters `/* */` on lines that already are already commented out are not affected when you comment and uncomment code as described above.

To comment out code:

1. In the C/C++ editor, select the line(s) of code that you want to comment out. If no lines are selected comments will be added (or removed) at the current cursor positition.
2. Right-click and do one of the following:

- To comment out the selected code, select Comment.
- To remove the leading `//` characters from the selected line(s) of code, select Uncomment.

Tip: Instead of using the context menu (right click) you can quickly comment out by pressing CTRL+/ or remove comments by pressing CTRL+\.
