My two cents: I've a heavy command line user. I have very strong demands
on my command recall capabilities. I find control-P to be the single most
useful keystroke in my repertoire. Command number recall *never* makes my
list. The zsh feature that lets me edit multi-line commands is a major
hit with me. Control-R, if incremental, works quite well, although that
isn't usually the case either.

People I work with use command number recall. The same people who never
fix their shell from csh to bash/zsh. The people who use the same thing
they first learned to use over a decade ago. A few of them even type 'h'
to see their history, then switch over to the mouse to cut + paste the
command - and if the line extends across multiple lines, they do multiple
cut + paste operations, because they are not confident in understanding
whether the lines are line-wrapped, or newline terminated.

Allowing these people to live in the dark ages doesn't appeal to me.
Certainly not if it takes effort to do so. :-)

I don't buy it either.

Cheers,
mark
