I understand that in OnSpecialKeyDown we can intercept the Back button
press (if keyCodeString = 'KEYCODE_BACK')  and cancel it (mute :=
True).

In that situation the app will not close, the form will remain open,
OnCloseQuery, OnClose, etc. will not be called and the app will
continue running normally.

However, I would like that after the above Back key is pressed, the
app should disappear as if the Home key had been pressed. By that I
mean that the app should continue running (well, actually it will be
paused) but free the screen as if Home was pressed.

So, after cancelling Back, What command do I have to execute to
achieve that?

I figured out the answer: call jForm.Minimize();
