Something new in this case?
It’s really a problem, because one needs respelling terribly often.
As in the english keyboard layout neutral-flat-sharp is mapped to “0” “-” “=”
it won’t work alike with a german keyboard, because “=” -> gets “`”, a key that only works as “decorator” for accented vowels.
As “-” gets “ß”, which works fine for “flat”, the smalles adaptive change possible is to give “sharp” to Shift-ß (that yields ?), that also works.
Now, respelling is conceptually very near to setting the accidental; it’s logical and straightforward to map this function to
Alt-ß and Alt-Shift-ß (or written alternatively: thats Alt-?).
Alt-ß works, Alt-Shift-ß definitively not.
Btw. AltGr on the key yields the blackslash. Could this be the problem? But Alt and AltGr are different keys!?
This should be fixed, quick respelling is really important (sometimes I still hit Enter, because I used it so often in Sibelius…)
