If the Delay to be provided is greater than 1 second, then maybe an alternate would be to use the Retry option available with Verify execution Property of the Type Into Activity.
However, If the application itself is made in the manner as to avoid any updates for a brief period of time, I do not think the Delay can be skipped.
Also, Is this happening after each field entry or only after the first few fields ? Also, Is there a involvement of the Enter key here, In some cases only after clicking on Enter the field values are auto generated. So Perhaps, maybe skipping the Enter Key at the beginning and only keeping the Enter key at the end maybe a possibility ?
The above suggestion is a bit stretched out as we do not know the exact application that is being used and it’s UI screens or it’s visual behaviour, but I hope the idea is understandable.
