There are some Blend Options in AnimMontage editor. When I try to see tool-tip of one, it shows:

And when I press Ctrl+Alt keys, new tool-tip appears:

I tried to see BlendOption's source code, but it only has normal comments.

Then where the advanced tool-tips’ data is? I want to try to make them.

Those are loaded from documentation files. Here is the doc file for that specific enum:

https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Documentation/Source/Shared/Enums/EAlphaBlendOption/EAlphaBlendOption.INT.udn

You can add your own by creating it in Engine/Documentation/Source/Shared/Types/YourClass/YourClass.INT.udn
The editor will automatically detect it and show you the ctrl+alt option.

You can learn the syntax by reading the existing documentation files.

Let me know if this is what you were looking for and mark the answer as correct.

Enjoy!

To add to Sveitar’s answer:

This will also work on a project and plugin level as well. You simply need to follow the same folder structure as what is in the Engine folder. You just need to add : “Documentation/Source/Shared/Types/etc…” folder underneath your base project or plugin folder and the engine will pick it up.
