Some Nano Questions?

[Hart Larry <chime hubert-humphrey com>]

Hi All:  I am trying to use nano more often than pico.  Even after I mention 
that editor in the Lynx config, it still runs pico instead.
Next, how can I run a global search-and-replace?  The manual implies a function 
kee which I don't have such as f14?
And lastly, is their a way like world-perfect where I can block text  and move 
it to another file?
Thanks much in advance
Hart
