Connect a mouse to your iPad
Pair either a wired or wireless mouse or trackpad with your tablet for system-wide control
When it released iPadOS 13, Apple let you connect and use a mouse with an iPad. But since it was an option within the Accessibility settings, it was limited in scope - something that has been rectified with the release of iPadOS 13.4.
Now there is full system-wide support for a mouse as well as a trackpad, effectively turning the iPad into a mini laptop. This is intentional, given the new Magic Keyboard for the iPad Pro has a trackpad built-in. Working on documents is easier as a result.
