[plt-scheme] Problem with french keyboard

(Old) problems with MacOS-X French keyboard.
To get the ~ in the DrScheme 202/203 editor, I must
type ~~~ three times then rubout two of them : the
sequence ~<space><space><space><space>... gets ~~~~...
the ~ key is stuck. Same with ^ and `
The sequence ~<space>n gets the spanish ñ in regexps !
De la mano a la boca se pierde la sopa :-)

Un autre français sur MacOS-X peut-il confirmer ça ?
