In the meantime i can help me with an macro.

– find/go to the wanted start position for the selection.
– set an bookmark (toggle: Ctrl+F2).
– find/go to the end position of the wanted selection.
– execute this macro:

o = document.selection;

	EndLine = o.GetActivePointY( eePosLogical );

	document.selection.PreviousBookmark();

	o.SetActivePoint( eePosLogical, 1, EndLine, true );

The same but wiith explanations:

	

	////Returns the line number of the cursor position:

	yPosEndLine = document.selection.GetActivePointY( eePosLogical );

	

	

	////Goes to the previous bookmark in this document:

	document.selection.PreviousBookmark();

	

	

	////Sets the cursor position:

	////bExtend: Optional. Determines whether to extend the current selection. 

	////If bExtend is true, then the active end of the selection moves to 

	////the location while the anchor end remains where it is. 

	////Otherwise, both ends are moved to the specified location.

	bExtend = true;

	xPos = 1;

	document.selection.SetActivePoint( eePosLogical, xPos, yPosEndLine, bExtend );
