I alway use "g~w" in vim. See ":help g~"

As others have posted, there are ways in nvi and vim. However,
since you posted to comp.unix.shell here are some macros that do it
using only POSIX functionality. These have been in my .exrc for
over 20 years (from the days when the only vi available to me was
the "real" one).

This is the output from "cat -v", so ^V is CTRL-V, ^[ is ESC, etc.

" =y, =Y macros - yank word (Word) onto line by itself: 2=y works
" (side effect - mark current position as `x)
map =y deumxO^[p
map =Y dEumxO^[p
"
" \R macro - common part of \l, etc. (overwrites text at `x with current line)
map \R A^V^V^[^[0iR^["xDdd`x@x`x
"
" =l macro - change upper to lower case over whole line
map =l :s/.*/\L&/^M
" \l (\L) macro - change upper to lower case over one word (Word): 2\l works
map \l =y=l\R
map \L =Y=l\R
"
" =u macro - change lower to upper case over whole line
map =u :s/.*/\U&/^M
" \u (\U) macro - change lower to upper case over one word (Word): 2\u works
map \u =y=u\R
map \U =Y=u\R
"
" =x macro - exchange case over whole line (slow if showmatch set)
map =x :s/\([a-z]*\)\([A-Z]*\)/\U\1\L\2/g^M
" \x (\X) macro - exchange case over one word (Word): 2\x works
map \x =y=x\R
map \X =Y=x\R

Well since you can do that in vim, and since vim in
compatible behaves more like vi than nvi does ... --Antony

Ooh! Now if only it had the other stuff I'm used to. (In particular, I'd
kill for a setting for "do infinite undo the way nvi does", because I find
that more intuitive.)

From my .exrc as it existed 22 years ago.
<esc> is a literal escape; ^V is a literal control-V.

" change word to lower case
map #3 i^V
<esc>Ea^V
<esc>k:s/.*/\L&/^V
JkJ
" change word to upper case
map #4 i^V
<esc>Ea^V
<esc>k:s/.*/\U&/^V
JkJ
