Help with a notation symbol

[Lake Sagatagan]

I really did try to find the answer on my own; it's difficult to use a dictionary when the symbols are ideograms. What does a horizontal saw-tooth notation over the staff mean? Sort of: ^^^^^^^^. (Specifically, I'm trying to decipher measure 18 of Andrew York's "Andecy.")

Also there, what's the elongated omega-like symbol mean?

Vibrato?

A picture would help.

Thanks Jeff and I'm sorry. I don't have the computer chops to post a picture here.

The symbol appears over two three-note, sixteenth-note passages. It would be difficult for me to apply vibrato that quickly, but that's why I'm studying, to make more possible. However, the mystery symbol seems to pertain to one note on an open string. I guess I could shake the guitar, but...

It could indicate a trill.

In flamenco music I'm reading, it means a rasqueado downstroke

Does it look like this:


Then it's probably a mordent, i.e. an ornamentation figure. (Trills are usually indicated with a "tr" abbreviation above the note).

Watch at about 1:33...he's indicating fretting hand vibrato in the notation.

Thanks for that video link Phil. I think you're right (and Mr. Beaumont too), it must be a vibrato marking.
It can also show like this in notation:


Maybe the op will confirm the symbol.

Thanks, all, for weighing in on my question. I will slow the video, linked above, and see how York plays the passage.

Interestingly, I eliminated the possibility that a vibrato was being indicated because I couldn't figure how to get that on an open string. But I realized that the person who supplied the tab choose to represent an "A" as played on the fifth string. That may have been a mistake. I'll bet the video will show York up on the sixth string, seventh fret, drop-D tuning. (York, himself, hasn't provided tab notation on any piece I got from him directly.)

Thanks also for recommending another way to find answers to this naif's questions. I don't know why it didn't occur to me to go to a video of the primary source. The most likely explanation is too painful to confront.
