// This is a variant implementation of the "keypress" sensor,
// utilizing the Jaiku "keyevents" component. Unfortunately the Jaiku
// codebase does not actually appear to have any code that uses the
// component, but hopefully we manage it without an example, and
// hopefully it actually does work.
