OpenSelectedElement
Controls which element is loaded after switching from multi-track into 1-track mode:
0 - the first element (i.e. the element from the top track of multi-track mode)
1 - the element that was originally loaded into OTM
When you drag one audio element into OTM, OTM (since version 1.3 or so) attempts to load a complete transition. With OpenSelectedElement=0, the first element of this transition is loaded into 1-track mode; with OpenSelectedElement=1, the element is loaded into 1-track mode that was dragged into OTM.

This parameter is only used for OTM versions 1.3.346.19 and higher patch levels, or 2.0.497.0 and above.
Possible values: 0, 1
Default value: 0
