Luke,
Thanks for the response. I am trying to help someone out on the Pygtk
list. I forgot to enclose his reasons for wanting to assign the key
press. They are below: It looks like he likes his keys set out in a
certain way. I am happy with mine the way they are! I used "z" in
isolation just to get the logic right. I know I can assign a function
to Z and make the Treeview move down one row and select the row below
but I don't want to have to do this for all the different buttons. I am
trying to do it without having to assign and call a whole load of
different functions.

I have attempted to answer his question but I am not sure I am on the
right track. Is there a better way to do it?

I highly doubt that what you want to do when someone hits a 'z' is to
generate a 'down' keypress.
What if the user assigned the down key to z?
then you'd have a
z -> down -> z -> down -> .... infinite loop.
What I expect you want is that each key, z and down, perform the same
action.
In other words, they both call the same function.
So basically what you'd want is something like this (non-pyGTK specific
code)
def aFunc():
print "Hello, World!"
bindKey = {'down':aFunc}
keypress = raw_input("What keypress do you want to perform?")
bindKey[keypress]()#this will call the 'aFunc' function if they type
'down', otherwise, it'll probably crash.
bindKey['z'] = aFunc
bindKey['z']()# now performs the same function as
bindkey['down']()#this does.
If you really do want to generate 'down' keypresses when someone hits
'z', please explain why, and I will try to the best of my abilities to
help you in that regard!
Good Luck!
