This tends to be less of a problem than you might think.  "Type behind"
as one person called it is great.  It allows you to do things like have
a smart terminal driver that remembers the last thing you typed so you can
go back and edit it (not like that !$ stuff in csh, but less powerful).

I make mistakes with the invisible type ahead.  Many times I do catch it
before it's too late.  With VMS you can do a ^X anytime the terminal is
not in "raw" mode and clear the current type ahead buffer.  How does one
do this under unix?  (Really, I'd like to know, but I don't think it can
be done if you have entered several commands...)

How do you see what you are correcting when you type the password to your
system.  It's the same sort of deal.
