I think what you want to do is to use a click plus a modifier key. So if your app uses a control key to make non-contiguous selections, your script would look something like this:
TypeText ControlUp (* Make sure to release the modifier *)
Note that you could also install and use the Windows text image generator (TIG) to make your script more dynamic. Instead of having to capture images of the row data, you can dynamically generate images of the data. That way you could quickly create data driven tests that used much more of your sample data. Let us know if you need more information on how that would work.
