Dynamics AX 2012 - Skipping controls on a form if they are disabled

I would like to skip controls inside a form whenever the user presses the tab key.  However, I only want the control to be skipped if it is disabled.  Otherwise, it should not be skipped.

How can I do this please?  I know that if you want a control to be skipped by the tab button ALWAYS, you can use the skip property on the control.  However, how can I skip it only if it is disabled?

Thanks
