This makes me wonder when the `apropos` command was introduced; surely
the name was also somewhat of an obscure joke ("what is apropos of
listing a directory?" is not exactly the phrase that springs
immediately to mind when wondering how to list a directory).
But the other form of it, `man -k`, is reasonable. Plan 9 called the
similar thing, `lookman`.

For the counter-example, I wonder if anyone ever
tried to type very much (verbose) DCL on VAX/VMS using a Teletype. :-)
I had occasion to use an ASR model 33 Teletype with VAX/VMS. Hated it. The
DECwriter LA36 was acceptable, though.
While DCL commands generally involved complete words, they could be abbreviated to the
smallest unique abbreviation. Thus one mostly typed DIR instead of DIRECTORY. Command
keywords also were be required to be unique in the first 4 characters--the DCL parser
ignored all but the first four. characters. The engineers at DEC's Marlboro MA
facility named one of their networked machines TWINKIE so that to log into it they could
type SET HOSTESS TWINKIE.
The terse Unix command verb style can be a steep learning curve for beginners. How is
one supposed to know that you say 'ls' to get a directory listing? And
unfortunately man pages aren't very useful for beginners because you have to know
what the command verb is in order to call up its man page. Unix lacks a place to ask
questions such as "how do I get a directory listing?".
