I have now implemented this, and I realize that the arrow keys aren't
enough. One must be able to erase a letter - this can be done with the
up arrow. But I also think that one should be able to get instructions
at this point. Can we add the space bar as a general help key? It should
be quite easy to find on the keyboard. Then hitting the space bar will
provide relevant help at all stages (will not work when a voter types in
a write-in candidate using the keyboard).
