When setting the Tab order in a Layout with a Tab Panel Control, I have discovered that Fields in table layers other than the front one cannot be included in the Tab sequence -- or, they can, but in practice those fields are ignored when the user tabs through the fields.

Is there a best practice workaround for this, so that, for instance, a user may Tab from the last field on the 1st Tab Layer to the first field on the 2nd Tab layer, etc.?

I'd think this is a common need . . .?

You can always use a script trigger on that field.

So, would it be an "On Object Exit" trigger tied to a simple "Go To Field" script? It won't hurt to leave the target field in the Tab Order, right?

Not trying to make this harder than it is, but sometime I try something like this all over my solution and then it turns out problematic for some reason....

You could use Go to Object to go to the next tab.
