Update: Sorry as commented bellow, It is possible to do it in Read Mode using notes.ini. Thanks for the comment.
FIELD $TabTable := "TabName";
You can switch tab of tabbed table in Edit mode. You need to name the table and put in special Field the tab name. FIELD $TabTable := "Tab01". So U can create your own navigation in on the Form very easily.
In case you want to hide the tab cations and make your own navigation you are not able to do it in read mode.
You need to enter the edit mode or to close and reopen the document.
Similar: To expand or collapse sections in read mode.
