* Is there ANY way of reading [GRAPH] and/or [CTRL] input, using some corresponding ASCII-code? As in: "A"=CHR$(65), [RETURN]=CHR$(13) etc?
* If not, is there an alternative way?
* Who can tell me which DEFUSR-adress is preserved for cleaning the keyboard buffer? I forgot...

* No, there is no ASCII code for CTRL or GRAPH. If they are used in combination with other letters they will have effect to ASCII code anyway.
* First question makes me think you are talking about BASIC. So maybe this helps:
if peek(&HFBEB)and2 then else ?"CTRL pressed"
if peek(&HFBEB)and4 then else ?"GRAPH pressed"
* DEFUSR=&H156
