One of the options we have available on iPadOS 13 is to configure the trackpad or mouse pointer to our liking. In the official Apple support channel they offer us a new and short video of the available functions and the configuration that we can make of the iPad pointer. This function is logically activated when connecting a wired mouse, a trackpad or an assistive Bluetooth device on the iPad so first of all you have to know that the function will not be available as the iPad has nothing connected.
It's simple, let's just Settings> Accessibility and there we can edit the contrast, we can hide the pointer when we are not using the trackpad, we can expand its size or we can even configure the pointer speed or inertia. This is the video that Apple offers us to make the personalized adjustments to the user's liking, it is best that you see it and that you yourself touch the options to adjust the pointer to your liking:
The arrival of the new keyboard for the iPad Pro and previously all keyboards and devices that can be connected to the iPad offer the option of using this pointer. It is certainly interesting to use a pointer to click on screen icons that you could otherwise touch, or simply use it to navigate through any app or tool installed on the device. In the case that you use a keyboard To control the pointer, you must activate the Mouse Keys function from Settings> Accessibility> Touch. At that point we have to choose AssistiveTouch and then Mouse Keys.
