How to use the win logo en lock

@Kingsmann22 

Good question. I've never used F* keys because I always use external keyboards. To answer your question, I have to turn my Open on (because I only use it once or twice a month to edit photos/videos of my grand children). I thought it has a lock symbol it could be the key I can use it to lock the keyboard (for example when go to down stair to get a coffee) but it did not.

The manual does not help at all, only

        

Hope someone can give an answer, I'd like to know too.

Note: Very interesting, few members asked same question before (from 2016) and no answer.
