So many interesting things to learn, so little time. I don't know how
to make/patch packages, and could learn a new computer language or a
few new WMDEs in the time learning a package manager would take. So I
do what I can: Submit docs on how to do it right. Anyone's free to turn
that into a package, if they wish.

Also, about dealing with Debian: If they don't let me on their mailing
list, I'm not giving them the time of day.

C: A set of settings good for any keyboard-preferring use who makes
heavy use of dmenu.

Putting it in examples is a good idea. The upstream default is
reasonable for all mouse all the time types, and so shouldn't
necessarily be replaced.

Also, the choice of hotkeys is purely my choice and would be unpopular
with most people.

I have no evidence of documentation that ctwm doesn't require more RAM
than KDE. Now I'm pretty darn sure it doesn't, but I don't know how it
compares to others. A brief useage in a Devuan Jessie Qemu VM indicates
to me that ctwm doesn't impact performance.

Then, in my script to run the VM, I set -m 128 instead of -m 1024. Both
ctwm and fvwm popped up almost instantly. LXDE was a little sluggish.
Xfce was a lot sluggish and took a couple seconds to assemble itself.
When I ran firefox with the -m 128 it took down the machine to a black
screen.

I set -m 4128, and Xfce came up twice as fast, and firefox ran
beautifully.

So it looks like ctwm is suitable, resource wise, for any realistic
computer you'll encounter today.

There it is folks: The preceding is why we need a new word. Easy trap
to fall into.

s/WMs/WMDEs/

Or change WMs to DEs, and then the whole sentence becomes false.

I'd add that Xfce can be a little sluggish.

For the most part I agree with you. Unless you encounter a low-resource
computer. And I'll add one other thing: Something I've subjectively
come to believe: Full featured computers running one of the very low
resource WMDEs are *extremely* snappy.

Regardless: My limited research tells me someone willing to get under
the hood and configure ctwm can match his computer's ergonomics
*precisely* to his needs.

OK.

I did make an improvement. My original email told everyone wanting a
dmenu-enabled, keyboard-centric high speed interface how to make it
with ctwm.
