i feel like i have been given the shaft

They didn't show how the reverse gear does it's job.  Granted it's because there's another gear between reverse and the countershaft and easy to figure out, but show it for freaking completeness.

I like this old video better--transmission stuff starts at about 3:00.

That one stops about halfway through, here's one that goes to the end:

Huh... weird.  The first time I watched, it was only about 5:40 long.

Also, Archimedes apparently talked. Very. Slowly.

The 'watching paint dry' video was apparently unavailable.

Yes, I only watched the video all the way through because I wanted to see that last, reverse, engagement.

So... all 4 gears keep turning, but the engagement sleeve determines which one is transmitted to the axle? How does that happen? Is there some mechanism inside the shaft that is not shown?

Kind of. The output gears (the big ones) spin freely on the output shaft. If you look closely, you'll see what looks like a skinny gear right next to each one. These are actually positive engagement clutches (dog clutches), and the output shaft also has its own. Sliding the sleeve toward one gear connects that gear to the output shaft, locking them together. The other gears spin freely at a faster or slower rate than the output shaft. You have to look carefully because it's a little hard to see, but you can kind of see it on that video. If they were to spin them more slowly and/or mark the gears, you'd see it pretty clearly.

...but do the splines reticulate?

After you learn how this manual transmission works you can move on to the automatic here with the Turbo Encabulator.

That's what I was thinking, aren't we missing something vital here?

That was cool.  Thanks Subby.

An unhelpful retort to a valid question.

Someone covered it above.

The very first gear on the input shaft is splined to the input shaft. It transfers power to the counter shaft. All the gears on the counter shaft are fixed to the shaft. The counter shaft gears mesh with the main shaft gears. The main shaft gears are free to spin on the output shaft. The sliding clutches or dog rings are splined to the output shaft. So, when you engage a main shaft gear with a sliding clutch it locks that gear to the output shaft.

Often direct drive simply couples the input shaft gear directly to the output shaft. Also, syncros are in between the sliding clutch and the gear. They simply make the transition easier by bringing the gear and the clutch close to the same speed.

A very small number of transmissions actually have a gear that slides back and forth for 1st and reverse. Otherwise all the gears are always meshed with each other.
