send "keyUp" / "rawKeyUp" ?

[Richmond Mathewson]

Either I did not explain things very well or you got hold of the wrong 
end of the stick
(or, most probably a bit of both: probably the latter as a consequence 
of the former).

Imagine, if you will, I need to know what an end-user's standard 
keyboard layout is.
Let's call our theoretical end-user Farhad, and Iranian who uses an 
Iranian keyboard layout
(something I don't know), and let's call our me Richmond owing to a 
slight lack of imagination
on my part; and I use a US English keyboard layout, which I know, but 
isn't useful information
under the circumstances.

Now if I click on the key that yields a rawKey of 113 I get a "q".

If Farhad clicks on the key that yields a rawKey of 113 he gets a "ق

And I am unable to type close-quotes there.

So I should like to find a way to fake someone pressing down on a key on 
their home-computer
to see what the keyUp result is.

Now I realise I cannot SEND a command telling the key on the keyboard to do
"a pianola" and depress itself (wouldn't that be fun?).

It would, however, be groovy if one could work out Farhad's keys without 
having him to
go "bash, bash" all the way along the rows of his keyboard.

Richmond.
