Thanks for your help, Black Lab.

You can choose any point on the video, from that chapter point forward, as the thumbnail for the chapter. Just double click on the thumbnail and navigate to the clip you want. For a title thumbnail you can choose from any point in the video.
But when I try that, I find that I can choose any point from that chapter point forward
on the same clip but not any point on any subsequent clips. For many people this won't make a difference, but if I have my chapter start with a five second long clip of a title on a black background, for example, then I can't select a frame from the actual video clip that follows the title. Is there a work-around here?
This example shows the issue:

This is from an hour-long production, and -- as you can see in the image -- I've scrolled as far as I can, and I can't get past the end of the current clip.
** EDIT **
I just figured it out! VS lets you select a thumbnail frame from anywhere between the current chapter point and the next chapter point, which could be one clip or several, but is not the whole video. But I think that is the best way to do it, on the whole.
