Jump to next field

i'm sure somebody else will have a better method for doing this but you can check in the OnInputChange() trigger of the control and activate the next control. The problem seems to be that there's no good way to get the value entered in your control. You can do some searches on OnInputChange and see that it's a problem. One thing you can do is put a global variable counter on the form and increment it in onInputChange(). Once you get to 4, activate the next control and reset the count to 0. It works but it's not the cleanest implementation. It will probably break if you use backspace for example. I'm pretty new to NAV so I'm sure somebody else will have a better approach but that's the first thing I thought of.

Or in some cases setting maxlength and AutoEnter on the editbox is enough...

Maxlength & AutoEnter are a great set of properties.
We keep all our item numbers at 5 characters for quick order entry!
Maxlength = 5
Autoenter = yes
\:D/

Now this is set on the field on the form - but once in a blue moon you might have an oddball that's more than your max length. - To get around that - you can simply add the field again to the form (example. sales line) place it all the way at the far right and don't use the properties on that field. this way for quick entry they can use the "regular" field but for those occasions they can use the other that has no limitations.
