The following bug report applies only to the Hog4PC on a laptop without any programing or playback wings and in keyboard "MAP" mode. I will test tomorrow on a Hog4PC with the wings to confirm if it is isolated only to keyboard shortcuts using keyboard "MAP" mode.
With the scene and list palletes unguarded mouse clicking the selected pallete will go on that scene or list, but I am unable to release the active scenes or lists by clicking and holding on the pallete while pressing the "Z" key for release.
It actually appears that none of the virtual playback functions are working while using the method of "Click and hold selected Scene/List Pallete + Mapped Keyboard Playback Key".
