	it also has a bunch of affordances --delete_word and such-- for editing
	a command line --a task that in the Plan 9 style is done with a mouse
	and Rio.

^w will delete the current word,
in the editors and in rio.  and ^u
the current line.  be careful though:
^w deletes the current _window_
in microsoft-land, which is bad news
once your fingers get trained.

some people said they didn't get this
yesterday, so since i'm talking...

g% cat /usr/rsc/bin/rc/"
#!/bin/rc

{
	if(test -r /mnt/acme/acme/body)
		cat /mnt/acme/acme/body
	if not
		cat /dev/text
} | grep '^[^ 	]*%[ 	]*'$1  |
	{echo; cat} | pr -t -n | sort -u +1 | sort -n |
	sed 's/^ *[0-9]+	//' | grep .

# the silly {echo; cat} gets around pr printing "empty file" when
# presented with no input.
g%

for example:

g% " mk
>>> g% mk
>>> g% mk test
g%

shows the commands i've run in this window
that begin with "mk", ripe for editing or resending.

(except the >>>'s don't get printed in real life).
