Title: Use only Back (not Home) for exiting from Help screens

It is a bad idea to use too many keys for the same function and also do
this non-uniformly (i.e. not in all contexts). The info at the bottom of
Help screen says "Back to close this page", so only KEY_BACK (but not
KEY_HOME) should serve this purpose. And if the user pressed Home twice
then the whole application would exit, so using Home here is a bad idea.
