Trying to perform the Ctrl + G (Go to line) keyboard shortcut, seems I accidentally activated a feature that pins the code the cursor was previously on.
After closing and reopening the file, things are worse; the code snippets still are floating over the screen, no matter if I move the Android Studio window.
I have searched keyboard shortcuts using this guide, but no luck.
Is there a way to disable or revert this?

Noticed by comment below and confirmed by myself: This happens after extracting a method.
