Shortcut to switch between displays

I have MacBookPro 14-inch 2021 running Monterey with an external monitor. I use both. I want an easy way to switch between monitors. Here is the use case. I'm watching a tutorial on the external monitor and following along on the laptop. When move to the external monitor I want the cusor to still be at the play/pause button. When I switch to the laptop I want the cusor to we wherever I left it. As it is I spend more time moving to cusor than anything else. It is easier to get another laptop to play the tutorial. That could work in this situation but it will not when I want to copy/paste open a file drag and drop etc.
I can add a second mouse it that would help.
