The issue here is that a common text editing key can also (if pressed
when focus is in the wrong place) instantly change your browser window
so that what you are editing is no longer visible _and_ it looks like
your edit has been cancelled and you have to start again (this being
what many people would assume if they saw the previous page again, which
probably has a big link called "Compose".) If there are other keys like
that, file bugs on them.
