After that, in the section `<Shortcut></Shortcut>`, we will change what we have to write to **call our snippet** \(the shortcut\) from `cw` to `cr`.

 In the previous section we mentioned two of the combinations that are used for formatting code. One of them [**CTRL + K + D**] is used for **formatting the whole code in a file**, and the second one [**CTRL + K + F**] serves if we want to **format just a piece of the code**. These combinations are called **shortcuts** and now we will give more thorough information about them.
