The explanation is simple: these keyboard shortcuts had to be reorganized, be tied to the display action icons shown at the bottom of the player window and complemented with a panel letting the user selectively enable and disable them. This is because many users complained in the past that the keyboard shortcuts interfered with other shortcuts used by the host or remote environment. Since the configuration panel is not ready, the shortcuts cannot be disabled and thus the decision was taken to not enable them, hurting people like you that were used to this handy feature. My apologies. I hope it will be of relief to know that work on this configuration panel has resumed and the shortcuts will be back soon.
