What is this screen?
that window comes by default with the haddock documentation
I think it should work as a quick "go-to" however for PlutusTx the links do never work (at least to my experience)
Why does it pop up?
F you are searching for some text in the DOM of the page
that window is located on top of the main content at the ```ħtml`` level so the search goes there first
Can It help me in any way / what use does it have?
It can give you a quick overview of what's on the page however the clicking on the Types usually doesn't work so it's not that useful
Is there a way to stop it from poping up?
you can open the browser console by pressing
J or by the three dots on the top left of the browser searching for
this will remove the window only for the current page, refreshing or re-access the page will have the window once again
