Underscore brings me to the start of a line

[uduse]

Somehow when I press _ (aka shift + -) in command mode, it brings me to the start of the line instead of using the black hole register. I couldn't find any related vim setting or key binding that may cause this problem. Anyone has an idea what's happening here?

This is expected behavior: :help _. Maybe you're used to having a remap like nnoremap _ "_?

Thank you for the reply! I was reading the docs and I thought " is something else.
