I'd think it very natural that given that Up, Down, Left, Right, PageUp/PageDown
all scroll the source window, so should Home/End.  When the console window is
not on focus, we can use ctrl-a / ctrl-e to move to start/end of line,
just like we use ctrl-p/ctrl-n to go "up/down" in history.

Yes, that.

I do not agree.  I know I'd give lots of use to Home jumping to the
start of the file myself.

Thanks,
