Really? That's interesting. What did <ctrl-s> do? On the terminal emulators
I have on hand at the moment, none of them are responding or behaving

I always assumed terminals had some form of paging ability, no matter how
rudimentary, but I see how wrong I was....

At the risk of showing my age, in the very LATE 1970s, there was a program at UNSW called 'pg' which did paging on CRT screens. There wete 24 lines per page unless over-ridden on the command line. The tool was real unix tool, lean and mean with only a few arguments. It was far less functional than either 'more' or 'less' but it did let you page through a file or STDIN nicely. You had to pipe things through 'col' first in some cases and 'pg' generally played nicely with half-line motions from memory (which is really being stretched). I liked 'pg'. More seems overkill. A shame we lost it. I think there is another tool out there are several tools called 'pg' in the last 20 years but it is not the same as the original. One is not even a pager but I cannot remember what it is.

There is a lean+mean tool called 'pg' on Github but it is no relation to the one to which I refer. It is super, super basic.
