He says no, but you've brought up a related issue.

There's an automatic behavior when a card opens or resumes: the engine 
sets the focus to the first control with traversalOn set to true. This 
has happened since day one, and mostly I find it annoying, and it 
requires work-arounds. On Windows, where buttons can have traversal, the 
first control may be a button. On Mac, the first control is always the 
first editable field (even though OS X lets you set up keyboard 
navigation through buttons.)

The only workaround I know of is to store the selectedChunk on 
suspendStack and restore it on resumeStack.

The selectedloc assumes there is an active selection, and is only used 
to find the physical x,y coordinates on screen. If you only need to find 
out where the insertion point is, use "the selectedChunk". That gives 
you a field and character reference. If the insertion point is not 
placed, the selectedChunk is empty.
