The problem is that some language might require you to write "For X press
Y", which is impossible to achieve here. I think percent-formatting
supports using keys, like

  "Press %{key} for %{action}" % {'key': key, 'action':dict[key]}

However, I would also like to hear what Paul really meant and also the
alternatives he proposes.
