I guess I wasn't clear, re Target Disk Mode. I didn't try to muck around with it at all. I didn't buy a FireWire 800 adapter (at least not yet), so the point was moot from that perspective.
More relevant, like Warren Buffet, if I don't understand it, I don't invest in it. My singular major leap of faith was to bump up to OS X, but that's as far as my skittishness will take me.
RE in Leopard you could add/change keyboard shortcuts via the homonymous tab on the Keyboard & Mouse Preference (System Preferences, Hardware):
There ain't no such thing in Lion; Keyboard is way pared down.
And I've done several Web searches to try to find that lovely little utility, but the only thing that pops up relates to "product key".
