How can I set anchors in Microsoft Navision with Studio X?

I today learned in your webinar that it should be possible to automate processes in Microsoft Navision even with Studio X. But I had to stop already when I tried to use the type into function in order to type a value into a Navision field because I couldn’t set anchors nowhere. How can I change this? Remarks: It’s an old Navision program from 2003 and I access it via remote desktop.
