Thank you - this is exactly what I was looking for - the simplest way of 
getting input.

I fully agree with you. The reason is that there are external criteria 
which we have to meet. The criteria requires keyboard input, and 
personally have only used Squeak for Seaside projects so didn't know how 
to do this simple thing :-)

Thanks again.
