I wouldn't think so ...
Shft + something is a bad choice, btw ... you
should consider Ctrl or Alt ...
And even though most DE's (and many window
managers) will allow you to define hotkeys I don't
think that any of them will allows scripting (which
is what you require) :}
So: Open a terminal with a hotkey, yes, be taken
to the same terminal with the same hotkey, no.
