I only really appreciated this while reading while reading about https://en.wikipedia.org/wiki/Alaska_Airlines_Flight_261

It's quite an interesting one if you are into that kind of thing.

Well an MD-80 does use trim tabs.

[VBprogrammer]

Not really. It trims via a moving stabiliser. You are confused because it has flying elevators and the pilot only directly controls the servo tabs which look a lot like trim tabs.

Ah yes, brain fart. Tabs for the elevator, jackscrew for the stabilizer.
