Using chrome os, i am completely unable to use accidentals by pressing alt+arrows. I don’t know if this is a bug or a limitation of flash on chrome os, but maybe if it is a limitation another way to input accdentals would fix this issue. (using arrow keys on ‘expanded’ mode or simply another hotkey?)
@2a03 yeah we are aware that some OS’s give people trouble with alt + arrow. You can also use ‘,’ and ‘.’ and raise/lower selected notes.
