How do I fold code for comment blocks inside method blocks?

Question

How can I fold comment blocks inside method blocks to be folded (outlined), just like methods and regions, etc.?

Answer 1

1. Select the block that you want to hide
2. Ctrl+M+H

This needs to be done only once. The block will become collapsible afterwards.

Answer 2

Edit + Outlining + Start Automatic Outlining.
