I enabled the item show focused module keyboard

[murav]

I enabled the item show focused module keyboard, but there is no change on the screen.
However, if I disable this item,I can see that 'you can hide the displayed module' by right-clicking on the blank area of ​​the top bar.
Where is the body of the focused module keyboard?
Do I need to set the mode in advance or something?

Could it be that you're using a small screen?

Please post a screenshot with the "Show Focused Module Keyboard" preference enabled.
