How to create named code blocks in Intellij?

When Intellij generates code for UI forms you can collapse the code block and it is named: "UI Designer generated code". It is possible to collapse a code selection but its collapsed representation is displayed as "...". Is it possible to give it a custom name? It would look similar to a collapsed #region code block in C#.

There is a shortcut for that:

Open Surround with menu, by pressing

Linux/Windows: Ctrl +Alt+T

Mac: Option ⌥+Command ⌘+T

And than choose <editor-fold...> Comments option

enter image description here

Or you can do it manually.

For Java/Scala it is:

//<editor-fold desc="DESCRIPTION">
   ___YOUR_CODE___
//</editor-fold>

For Python it's almost the same

# <editor-fold desc="DESCRIPTION">
   ___YOUR_CODE___
# </editor-fold>

Example:

//<editor-fold desc="Main">
public static void main(String[] args) {
    System.out.println("Hello World");
}
//</editor-fold>

//region Description

 ... Your Code ...

//endregion

They have implemented region-support now!

From http://youtrack.jetbrains.com/issue/IDEA-80636

Currently Intellij IDEA supports two basic types of custom folding comments:

NetBeans-like:

//<editor-fold desc="...">
... code ...
//</editor-fold>

And VisualStudio-like:

//region <...>
... code ...
//endregion

Note that line commenting symbols for "region...endregion" can be changed from "//" to "#" if the '#' character is supported by a language. But by default custom folding comments use the same comment characters as normally used for language line comments. Instead of typing the comments manually, in many cases you can use Ctrl+Alt+T (surround with). Please submit separate issues if you find that something doesn't work as expected.
