If I learn how to do that, I'm sure that will be the first thing I'll 
use it for ;-)

Mhh, just when I got used to jumping to the beginning/end of a 
multi-line buffer with a double keypress of HOME/END ...

and on single-line buffers completely equivalent to what my code did 
which is obviously going to be the predominant use-case.
