Idea Summary
It would be a great feature to be able to navigate to the next cell to the right when hitting enter on the numerical keypad. It would make sense to enable this as a declarative control as it is a thing one might want even if the team is staying in the nocode - lowcode model.
Hitting enter and getting to the next editable cell to the right or to the first on the following row would be ideal for some use cases.
Today it is not possible as navigation occurs before Dynamic Actions get access and handling this would require messing with the code APEX ships with.
Use Case
The typical use case would be a data entry scenario where the user ends lots of data using the numerical key pad. Such users are much faster working the data with just one hand. They tend to come from a solution where this was possible. To them not being able to do it that way is forever going to be viewed as a limitation caused by APEX.
Preferred Solution (Optional)
My preference would be for this particular use case to be a toggle in a declarative way for the region.
