The same thing happens again and again. When Apple introduced a new beta version of its operating systems, system experts moved these updates to look for differences with previous versions to get the news ahead of anyone else.
In this case It looks like they've been able to get to a previous phase of iOS 14, and they're getting some improvements regarding mouse controls and keyboards with trackpad on iPads.
Program Specialists 9to5Mac was able to access the latest version of iOS 14 and by reading their code they found important news. In iPadOS 14 there will be new mouse support. There will be improved control of them and new directions.
Looks like it's going to be a macOS-like control. One difference from Macs is that the signal may disappear after a few seconds of inactivity, to return control to the touch screen. If a mouse or trackpad is touched again, it will appear again.
There will be different visualizations to show the directions depending on the work done by the cursor, such as changing the arrow title with one hand, when the task requires it.
Integration has also received support for new smart keyboards. Two new identifiers for two new types of keyboard have been seen.
There are obviously no details about the design and size of these two new keyboards, however To see the tasks they are able to perform, they will most likely be standard laptop keyboards, with a keyboard at the top and a trackpad at the bottom.
