A box opens when my pointer passes over "printf"

[jkt]

I imagine that a box opens when I pass my pointer over lots of things other than printf. I’m looking at the printf case now. The box shows me a list of other instances of printf being called. WOW!

What is this feature called? How do I turn it off?

Thanks in advance.

I think "show_definitions": false, will disable this. Not sure if there is a way to keep definitions but disable references… Maybe "show_definitions_references_limit": -1
