Regen question
I have a 2022 6.7 Lariat Super Duty.......at about 3400 miles.........I have never seen anything on the dash that said anything about a region.
This morning it was 10 deg. and I hit the remote, it started as usual, and after a few minutes went to 1000 RPM, and ran that way for a few minutes, until I went out and pushed the button, and let it run for another 15-20 minutes. it continued to run at an elevated RPM until I went out and drove it for about 20 minutes...........
Was it in a region? If so, why don I not see anything about it?

Don't stress about regens... What you are describing sounds like the elevated idle for cold temperatures. The new trucks do not tell you when they are doing a regen. it does it while you are driving and you might not even know (maybe reduced MPG and a metal burning type smell). If you don't tow your truck has done a regen probably 6 times or so. if you tow or haul heavy it did a passive one while you are driving and you didn't even know it.
Drive you truck, enjoy it. If the dash ever says "drive to regen" or whatever the statement is, I've never seen it in 15K miles, then go for a drive!
I came from a 2006 Duramax and obsessed about this stuff. 16,000 miles in my 2021 F-250, I just drive it and let it do it's things. This exhaust filter and DEF stuff has been around long enough that they have it figured out.
now, back to my bourbon and shopping cars for my daughter....
Edit: you asked what a regen is. It's the process to clean out the diesel particulate filter on your truck. Again nothing you need to worry about unless you drive tons of short trips and never haul or tow anything. More bourbon and my responses will get longer

It's more about the miles and conditions you drive in vs. just the speed. The truck will tell you what to do.

Then the truck has taken care of it without needing any intervention from you. I have never received any type of notification on mine.

You'll smell it when the truck gets hot during a regen. If all you did was stop and go driving, short trips and never allowed the truck to get hot then there might be a reason to wonder. As long as you are completing regens, then there's nothing to worry about.
I monitor my truck with a Banks iDash 1.8. The truck lets me know when it goes into active regen as does the iDash. The iDash hits first. I monitor Regen status, Soot load percentage, EGT1 and EGT4 amongst others.
As to the elevated idle, it does that when it's colder out to get the engine warmer quicker. Mine does that as well.
As to this attitude that there's nothing to worry about, I disagree. If the regens are not completing, you can or will eventually get a "Drive to Clean" message because the DPF is loaded.
The newer trucks do not tell you there's an active regen happening. The 11 to 16s do.

Any other questions, don't be shy.

Everyone had great recommendations. One more....do NOT idle these trucks for long periods. You mentioned 15-20 minutes. That's the single worst thing you can do to these modern diesel engines.

I haven't always used my engine block heater this winter, but when it's got really cold I have. It puts the oil temp at about 75 to 80 degrees. I usually have heat with the snow melting after a few minutes of idle time. Plus it makes it easier for the engine to start in the cold. I'm not worried about the engine not starting as it will, I.just want to minimize wear and tear on cold starts.
