How To Pair a Bluetooth Mouse with iPad or iPhone iPadOS 13 4

How to use a mouse with your iPad or iPhone

Go to the Settings app
Press Bluetooth.Go to the Settings app
Press Bluetooth.
Make sure Bluetooth is toggled on at the top. (The toggle will be green.)
Put your mouse into pairing mode. If your Magic Mouse 2 is unpaired, you should simply have to turn it off and on again for it to show up.
You should see your device appear under a header in the Bluetooth interface called Other Devices.
Press the name of your device.
You might get a “Bluetooth Pairing Request.” If you do, press Pair.
Your mouse should immediately start working. You’ll know it’s working if you can see the new circular pointer moving around the screen.

You can customize your mouse experience by going to Settings General Trackpad & Mouse. There you can change the tracking speed and choose whether the “Secondary Click” i.e., “right-click” will be on the right or the left. You can also turn off Apple’s “Natural Scrolling,” which I’ve personally never found natural.
