There is an excellent plug-in called AMS Smooth Zoom-V1.3 by Anton_S. For some reason it is no longer available from Extension Warehouse but it is available free from SketchUcation. It will drastically change you mouse zooming experience to the point that you will never want to work without it. I have used in versions 2017 & 2018. I believe it has been updated for 2019. You will also need to download the AMS Library V 1.6. Some users have complained that it zooms too fast and is not controllable. I have never had a problem with it. It will zoom in or out very smoothly quite fast. To stop it, or slow it, just left click your mouse and it will stop the zoom.
I also use a 3D Mouse. You get much more additional control with it. I don’t like a lot of fancy programmable buttons. 3D Connexion makes several models. I prefer their basic SpaceNavigator. Mine is Wired and uses a standard USB port. If you are using a Laptop You might like their wireless version. They are smaller than a mouse. Try using your regular 3 button mouse on one side and a 3D mouse on the other side of your keyboard along with AMS Smooth Zoom. You will never go back to anything less once you try both. The 3D mouse I use is available at Amazon or on E-Bay for about $100. The button versions cost much more but shortcuts can do the same as the programmable buttons faster.
The 3D mouse I mentioned also works great in other programs like Photoshop. You can also use it with any ordinary browser to smoothly scroll, line by line when reading anything that’s written.
