In RDE, the
toolbar is enabled. This allows you to configure what happens when you add a new record. You can use this option to select which fields to copy or increment and optionally force the cursor into a selected field after a new record is added. Auto-copy settings are local and can be disabled using the relevant option on the form.

Example showing the Auto-copy setup function opened using the
toolbar button. Here, the Copy function has been edited to copy certain fields and to increment the NUMBER field each time a new record is added.
