i've multiple .htm on how-to-use screen saved but have no reason to
use it yet (one CPU on the network).
for anyone else looking to save history across reboots:
I set it all up by finding [2] .zshrc's on the web, and setting up the
most-appreciated [1] common parameters in a local .zshrc. I've yet
(after many years) to understand most of them, as it was
set-and-forget. I'd be somewhat lost if I tried to do the
same from the manual pages.

1... either commented in the .zshrc file, or in one or two zsh-advocacy articles
2... finding and printing

Does that reflect lack of computing power or lack of complexity?
If it's the former:

1036 9716 0.0 0.1 7532 3016 ? Ss Jul26 8:50 SCREEN -c
1036 30119 0.0 0.1 10520 3944 ? Ss Jul24 41:53 SCREEN

That's 50 minutes -- 0.1% -- of computing time in a month.

If it's the latter, well, it all depends on how much you use the command line, I guess, and how much you like moving your hands from the mouse to keyboard and back. On a laptop or special keyboards, it's only a slight gain in productivity.
