Keyboard Doesn'T Work In Matrix Editor?

maybe it became optional, or is this my computer? anyway, when the matrix editor is open, no more dedicated keystrokes are avaliable, instead, all i have is the pattern editor behavior… (ex: return doesn’t mute/unmute anymore, etc…) anybody?

See [To Keep Or Revert?] Matrix Blocks Dont Respond To Keys Anymore? for the whole story please.
