Trying to learn the Z80 CP/M 2.2 ED editor.
We take the power and flexibility of out current editors for granted.
40+ years ago I started my programming career on Apple IIe and it had a similar editor that at the time was state of the art but looking back now I wonder how the hell I ever got anything done.

True, but trying to find a way to transfer .asm files to cpm CF card and assemble them on the device so I can develop on my PC upload the file.

Interesting project you have! I suppose you've looked into using Kermit for data transfer.

I have, but I've spent a lot of time getting the device configured, CPM loaded, CF card initialized and stabilizing everything.
I spent way to long on a problem with a DS1233 (Supervisory Circuits 5V EconoReset), it was holing the reset line low and when I touched certain parts of the board the SIO would output the startup message but after stopped. So I replaced the DS device with a 10K pullup resistor and it works just fine now. But not being an electronics guru it took some time to trace down.

I used to write COBOL using that - you had to be careful not to use tabs as it sent the compiler (Microfocus) crazy.

Used it only a little on CP/M and hated every moment of it. My colleagues were raving about it but I just couldn’t stand it and its silly control keys for cursor movement.

You had an editor? I had these 16 toggle switches, and two buttons - Load and Run.

Yup, that's the one. My predecessor at the lab where I worked built it, nothing worked, so he ripped all the wires out of it, threw away the documentation and quit. I still had the 1975 Popular Electronics article, and from that I was able to figure out where all the wires needed to go. It still didn't work. Then I found and repaired a solder bridge on one of the four 1k RAM cards; all ran perfectly. I got a S-100 breadboard and built an interface circuit to let it talk to a ASR33 Teletype and all was good in the 'hood! Fun times!

A much simpler time.
I've been retroing it for a while now, Z80 boards running CPM 2.2. It's been fun but frustrating as hell.
I bought some kit boards on ebay and populated them and they kinda work but having intermittent problems that are driving me up a wall. I know just enough electronics to be dangerous and the firmware I'm using is supposed to be compatible but then again not sure.
I'll keep on truckin' and eventually I'll either solve my problems or throw the damn thing out the window.

I used to write C programs in some editor (Apple Writer?)
Then I would run the file through a C program that would convert the output to a form that the C compiler would compile.
I think the problem was it did not like the end of line characters?
The editor was more usable than the only other editor I had. But I did use that second editor to write the program that did the conversion.

We were running ProDOS on the IIe, it's been 40 yrs ago now but it seems that the editor was a little more user friendly?

That is what most JavaScript haters sound like to me...
As an immature dev, I used to dis on COBOL. I worked with a COBOL developer on a VB app (yeah, go figure) who was left behind the times. He tried to explain "code 88s" (level 88 numbers) to me, and I was like "what the fudge". This dude was left behind and couldn't hang in the more modern world as all he knew was COBOL... this was about 20 years ago. Boy, did I feel superior... here I was all relevant and he's not. Clearly, COBOL must be a steaming pile of poo since it wasn't making sense.
Twenty years later, I did something called growing up -- sorta.** After studying the financial markets for a long time too, I've gained a better appreciation for context and history and where we came from to build up to today. Should devs stay modern? Yes. But, my disdain for COBOL more so stemmed from knowing nothing about it and its history and time and place, etc. and this guy who did nothing but format code all day that someone else wrote. As in, my reasoning was dumb, and a dev who uses COBOL and stopped learning is not the fault of COBOL itself. The more you know, the more you realize you don't know, after all.
If people want to know why I'm defensive of JavaScript? It's because 99.99% of the conversations I've had on CP about how JS sucks was by people who know little about it. I don't meet many JS experts here, but I do get the snickers, etc. I used to defend Macs on here twenty some-odd years ago for the same reasons. Despite their flaws like still using cooperative multitasking, just like 16-bit Windows did. But, don't you dare 'dis NTFS, despite the fact it was butchered in its early years... at least it fragmented less. Why, it's a bunch of Windows devs... of course they're gonna hate Macs (I don't love Macs at all now btw)... just because... yay tribalism.
Like when is enough, enough? Will programmers ever grow up? Why do we take 5 seconds to judge something and move on? When .NET first came out, I refused to use it because I wasn't going to use something that used an intermediate language (yes I know it compiles)... yet I do most of my work in JavaScript these days. Talk about irony. And yes, there objectionably better technologies than others (sometimes crap does suck), but the rationale I usually see for deeming good or bad is tenuous at best (I'm being nice here).
I could give more instances, Vulkan/WebGPU vs OpenGL/WebGL, etc. but y'all get the idea. Why can't we not have an opinion on something we know little about?

Because we all like to think we do know something about it. And if we don't like someone's opinion it does not automatically mean that ours is better. I had a fairly long spat with someone a couple of years ago about the UK's decision to leave the EU. He believed one thing and I believed the opposite. In the end he got rather up tight about it and I haven't heard from him since. But I still respect his right to that belief.

Agreed, but I wish more people didn't think their opinion was better. It's been my experience they do.

Am reminded of an incident a few decades back, in India, with a renowned Physics professor, and a traditionalist (read ancient Indian tradition).
The Physics Professor was giving a public lecture, and routinely mentioned that tradition is all incorrect. In the audience was this long practitioner of tradition, and he got up and said openly that "Your physics is incorrect". The Physics Prof got angry, and here is the conversation that ensued in that lecture hall.
Physics Prof: Do you know the history of physics, where so many great physicists have discovered facts. How can you say that Physics is incorrect. You are unscientific. You don't have a scientific bent of mind. You don't understand Physics. You have not studied Physics, and have no right to comment on Physics.
Traditionalist: You say that you are a scientist. From what I know, Science has these steps - Theory, Experiment, Observation and Inference. Yes, I agree that Physicists have propounded theories about Mechanics, Heat, Acoustics, Optics, Electricity, etc. and have done experiments, made observations and only then have they made inferences about the theory propounded. And you have studied all of this, and done experiments, made observations, over several years/decades.
Traditionalist (continuing): Now, coming to my tradition, what theories have you studied? What experiments have you done, and what are your observations? Without doing any study, experiment or observation, how could you jump to the Inference stage and conclude that "My tradition is incorrect"? You have not studied the scriptures about tradition.
Traditionalist (continuing): Did it not occur to you to apply your own scientific principles in the study of tradition also? Having spent none or very little time in the study of Theory of tradition, having not even attempted any Experiment, without any Observation, how can you adversely comment in a public forum about tradition? Did you give yourself the right to do so? You are not a real scientist. If you are merely expressing your opinion, then it is not science, if it has no backup of theory, experiment, or observation, because it is not based on facts. In fact, it is you, the so-called Physics Professor, who is not having a scientific bent of mind. A real scientist should have an open mind about all fields of enquiry, and should have no prejudices or biases against anything. Yes, I intentionally said that "Your Physics is wrong", but only to show your absence of logic, scientific thought, scientific temper. I have spent years, decades, and have done serious enquiry, questioning about my tradition, consulted several experts, and have done several assessments about it; of which you have not even an idea.
The Physics Professor could not reply.

The truth usually lies in the balance what has been and what is yet to be. Like, historically we used to bleed people who had a disease. Turns out that's really not a good thing. But, there are things that did work that we lost. For instance, it doesn't take a genius to realize processes foods and profit over substance in our food supply takes its toll. But, that won't stop commercials from advertising filth like it's yummo. It won't stop doctors from rarely considering food intake as part of the diagnosis. Let's just spray some more chemicals with no real studies and insult anyone who disagrees, despite not knowing the difference between a carb and a Cadillac.
So, it's a balance. Sometimes getting rid of the old is good; sometimes it's not.

Why do you ask? Is rat poison chemically related to blood thinners?
