HIdding The Mouse Cursor

I am using Retroarch and I am using the N64 Core. is ther a way to hide the mouse cursor in RL or is it done in Retro Arch

Sorry for the DUMB question I just cant remember how to hide it

The cursor is supposed to hide itself after a few seconds. You can also hit F11 to do a mouse-capture thing.

I think it shows when there are overlays onscreen, though.
