There are no keyboard shortcuts.  If you go to Edit-->General Preferences-->Interface there you will find all the possible things to assign a keyboard key to activate the command.  There are no camera movements listed. You can select a particular camera, but not control the movement of that camera via the keyboard.  You can use the mouse on either the Camera Control ball in that window OR use the mini ball in the upper right corner of the Poser window.  Either of those will move the current camera view around.  The most likely reason there are no keyboard shortcuts is that the Current View Camera and the camera selected via the Parameters control panel are not the same.  You can have the View camera set to Top (looking down on the scene) and have the main camera selected in the parameters palette and the controls will move the Main Camera which you can watch from the Top View to put it where you want.  So unless you select both the View camera and the Parameters for that camera then the movements you make with the dials won't be visible until you switch views
