You cannot poke values into the keyboard register.
You can, however monkey with what you get from GET.
10 PRINT "Press keys to see their values."
11 PRINT "Type OA-Q to quit."
20 GET K$:K = ASC(K$+CHR$(0)) + ( PEEK(49249)>127 ) * 128
21 K$ = CHR$(K) : REM kinda optional
30 PRINT K,
40 IF K = 209 OR K = 241 THEN 99 : REM OA-Q
90 GOTO 20
99 END
(The +CHR$(0) is to prevent an illegal quantity error,
if the user types ctrl-@.)
