App to auto move the cursor to "Continue" and "Accept" buttons?

I don't know what to search for in the archives, but wondering if anyone knows of an app that will automatically move the cursor to the "Continue" and "Accept" buttons when installing or having to enter passwords. Though I'm not a big Windows fan, I do appreciate the option to have the cursor automatically moved to the default option when the user is asked to acknowledge something with a mouse click... particularly on a portable computer. I'm looking for something that reduces scrolling around to the box and places the cursor right there. Some might see this as lazy, so feel free to joke away 😉 Perhaps this feature is built-in to OSX and I just don't know how to access it... honestly I can't imagine why it isn't an option, but maybe there's a good reason. Thanks for any suggestions.
