Carl - Thanks for your note.
By now you've probably read that I did find Daffyd's tutorial, so subtitles and Wave Editor now make sense to me. That wasn't the case when I wrote the post which you quoted. Following the tutorial, it did appear to me that one first had to click on the "sound track" (the part of the video track which contains the sound recorded by the camera as video is shot) in order to place a subtitle. Working with subtitles since then, I see that it's only necessary to click on the subtitle icon to the left, and then follow the steps. All of this works just fine for me, now - but it didn't until I found the tutorials.
I do understand the difference between a title and a subtitle, but thanks for pointing that our again. I'm sure you were not implying that I could not see the separate "sound track" icon. I'll get around to learning how to use that, to add other sounds, at some later time - maybe quite soon.
At any rate, whatever the correct terminology is, the subtitles do work in the location I'm describing, and it's the same location Daffyd used in his tutorial.
The PD forums are among the most helpful ones I visit but I've come to realize that no matter how precisely I try to describe things here, I'll often be misunderstood. Another example in the current thread is Steve's observation that a honking car horn, incidentally recorded as a video is shot, is not "background noise". Who would have thought that it was not "background noise? Not me. But okay, this forum has its own set of terms and I respect that. I will probably never learn to be precise enough to satisfy the contributors to this forum but I can live with that, and I'm grateful that you all continue to be available to help me.
