When I edit curves and am in the RGB channel, after moving the point on the histogram, I can confirm the correction (enter) or cancel it (esc).
When I select any other channel, the (enter) and (esc) keys stop working. In this case, to confirm the names, i must first click on the window, or on the OK button 😭
