Here's a part of an article I've posted before.

) echo "xxxxxx" )

	:map * :r!do-command^V^Mi/^V^["qdd@q^L

...where `do-command' is:

	#!/bin/sh
	# do-command: read a command and execute it 

	awk 'END { printf("\t\t\t\rCommand: "); }' < /dev/null > /dev/tty
	read cmd && eval "$cmd"

In your case the map would be something like:

	:map * :r!read_and_echo^V^Mi:%g/^V^[A/d^V^["qdd@q^L

...where `read_and_echo' is:

	#!/bin/sh
	# read_and_echo: read a string and echo it 

	awk 'END { printf("\t\t\t\rString: "); }' < /dev/null > /dev/tty
	read cmd && echo "$cmd"

You might want to change the `\t\t\t' sequence to an appropriate number of
spaces.
