We are opening this specification up for comment before we start implementation, currently scheduled to start on 19 October 2020.
At the start of text, it would be helpful for the keyboard to select an appropriate layer. For the purposes of this discussion, this feature should only apply to a standard text control, and not be activated for email, numeric or other types of input controls.
For most Latin script languages, an appropriate layer for start of text is the
shift layer. This is certainly not true for other scripts or for a subset of Latin script languages.
Similarly, at the start of a sentence, for most Latin script languages, the
shift layer should be selected.
