How to detect when user press ESC and do something in shell script

I want to create a poll in a shell script:

echo "1 - What is your name?"
read name
echo "your name is $name"

echo "2 - What is your country?"
read country
echo "your country is $country"
...
...etc...
...

I want if the user press ESC in a question, cancel the question an jump to the next question.

Thanks! I keep in wait for possibles answers!

If you end up using bash shell, you might be interested in the "trap" command, which allows you to trap and act on interupts (e.g. ctrl-C)
