iOS 12: keyboard cursor mode on non-3D Touch devices, + possibly improvements to 3D Touch input recognition
With 3D Touch, users can press on their keyboard to enter a text cursor mode which would allow them to easily and quickly move through and select text in a text field. However until now this wasn’t available on devices without 3D Touch (iPads aside, where the mode is activated by swiping on the keyboard with two fingers).
iOS 12 has introduced the ability for these devices to access cursor mode. To do so, press and hold on the space bar; once the button characters disappear you are in cursor mode. You can lift off the screen and cursor mode will remain active for a short time, allowing you to quickly scroll through large amounts of text easily.
Improvements also seem to have been made to the 3D Touch input management for this feature. Previously on iOS 11, if you attempted to use 3D Touch immediately after typing something the keyboard would often become confused and fail to recognise the 3D Touch input (interpreting it as normal touch interaction instead), requiring the user to lessen their input pressure and reapply it. So far in the beta this seems to have been remedied, and I haven’t noticed the issue pop up a single time (anyone else had different experiences?)
