How to easily search for opened file includes?

In some files I want to find any files that have included it when it's not obvious or available from a Cmd-click on a function or var etc, but right now the easiest way I can find is to right-click the file tab's name, select Copy Relative Path, then right-clicking the Project top-level folder and selecting Find in Path, then pasting the copied relative path of the file and editing out the parent directories...

It's a chore even thinking about these steps.

Is there some hotkey to show any files that include the file?
