Ctrl + Alt not bringing up full parameter description

In following the Unreal Editor Fundamentals - Materials tutorial, holding the Ctrl + Alt keys should be displaying a full description of the parameters details in the Material editor; this is not working for my installation of UE 4.25.4. Would someone know where specifically to turn this function on? I just have not been able to find it. thank you. Please see screenshot. The image on top is from the tutorial (shows the full description) and the image below that is my UE not showing the proper full description. Thank you for any assistance.

Does it work with AltGr a.k.a. right Alt key? Just right Alt, no Ctrl. Also, is this only in the material?

Hi,
no it does not unfortunately; good thought though, thanks. I hadn’t considered that possibility.
