I'm not sure that the "same" keystrokes can be used. The main limitation 
is that the OS, browser and screen readers have already commandeered 
many of them for their own purposes. For example, in my testing I could 
make control-P do something on my web page but in IE is still causes the 
print dialog to pop up. On Firefox though I can actually take over 
control-P and make it do only my function. Alt-P is free so in my 
example I could use that instead of control-P to implement some 
behavior. Similar substitutions may be made for defined alt 
combinations. For example alt-t in IE brings up the Tools menu but 
control-T seems to be clear. So if we want an IE friendly solution we'll 
have to steer clear of any keyboard combinations which are already in 
use which limits how close our web widgets can emulate keyboard controls 
of OS-native widgets. Best we can probably do is "similar" key combinations.
