Describe the solution you'd like

Currently in version 16.0.138 of Keyman for Android, long-pressing a particular key shows key(s) as pop-ups to select one.

After focusing the pop-up key using touch, releasing the touch will trigger that key.

If we can make focus to the first key among the pop-up keys set by simply long-pressing only, it will be useful to users to type using keys that have one option under long-press.

Kind attention is invited to this matter to add to a future milestone.

If we can make focus to the first key among the pop-up keys set by simply long-pressing only, it will be useful to users to type using keys that have one option under long-press.

My concern is if we default the focus to the first key among the pop-up keys, how would the user "cancel" the long-press? I can see a common case where a user is discovering what the longpress on each key is, and likely won't want that output by default.

• Default will be selectable by keyboard designer -- not necessarily the first, and may be none.
• Where there is a default will be indicated by highlighting it in the longpress -- the normal selection highlight.
• Given that cancel is not the preferred default action for a longpress, the user can cancel the longpress default by sliding outside the 'acceptance' area -- e.g. south of the key cap, which would then unhighlight the default and indicate visually that no output would occur when they release their finger.
