       playbackOptions([animationEndTime=time], [animationStartTime=time], [blockingAnim=boolean], [by=float], [framesPerSecond=boolean], [loop=string], [maxPlaybackSpeed=float], [maxTime=time], [minTime=time], [playbackSpeed=float], [view=string])  
Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.
      playbackOptions is undoable, queryable, and editable.
      This command sets/queries certain values associated
with playback: looping style, start/end times, etc.
Only commands modifying the -minTime/maxTime,
the -animationStartTime/animationEndTime, or the -by
value are undoable.

Query of edited option. | 
In query mode, return type is based on queried flag.

		  | Long name (short name) | Argument types | Properties | 
		
	
	  | loop(l) | string |     | 
	
	  | 
	      
		|  | Controls if and how playback repeats.  Valid values are
"once," "continuous," and "oscillate."  Query returns string. |  | 
	
	  | minTime(min) | time |     | 
	
	  | 
	      
		|  | Sets the start of the playback time range.  Query returns a float. |  | 
	
	  | maxTime(max) | time |     | 
	
	  | 
	      
		|  | Sets the end of the playback time range.  Query returns a float. |  | 
	
	  | animationStartTime(ast) | time |     | 
	
	  | 
	      
		|  | Sets the start time of the animation.  Query returns a float. |  | 
	
	  | animationEndTime(aet) | time |     | 
	
	  | 
	      
		|  | Sets the end time of the animation.  Query returns a float. |  | 
	
	  | playbackSpeed(ps) | float |     | 
	
	  | 
	      
		|  | Sets the desired playback speed.  Query returns a float. |  | 
	
	  | maxPlaybackSpeed(mps) | float |     | 
	
	  | 
	      
		|  | Sets the desired maximum playback speed.  Query returns a float. The
maxPlaybackSpeed is only used by Maya when your playbackSpeed is 0
(play every frame). The maxPlaybackSpeed will clamp the maximum
playback rate to prevent it from going more than a certain amount. A
maxPlaybackSpeed of 0 will give free (unclamped) playback. |  | 
	
	  | framesPerSecond(fps) | boolean |    | 
	
	  | 
	      
		|  | Queries the actual playback rate.  Query returns a float. |  | 
	
	  | view(v) | string |     | 
	
	  | 
	      
		|  | Controls how many modelling views update during playback.
Valid values are "all" and "active".  Query returns a string. |  | 
	
	  | by(by) | float |     | 
	
	  | 
	      
		|  | Increment between times viewed during playback. (Default 1.0) |  | 
	
	  | blockingAnim(ba) | boolean |    | 
	
	  | 
	      
		|  | All tangents playback as stepped so that animation can be viewed in pure pose-to-pose form |  |
