FYI: ignoring the distinction between Left and Right Alt keys can be a
nuisance for people who use Keyb.COM to support foreign (non-US) keyboard
layouts, because they expect the Right Alt to produce some actentuated
characters.  I suggest an option to let these users to get what they want. 
(Emacs on MSDOS has such support in its keyboard code.)
