With Maya’s animation controls, you can key objects, manage your scene’s timeline, and play back animation. See also Animation controls.
To display the Time Slider
Hiding the Time Slider provides more Maya view space. See also Time Slider.
To display the Range Slider
Hiding the Range Slider also hides the Animation Preferences button and the Auto Key button. For more information, see Range Slider.
To change the current time
Where you click with your mouse becomes the current time and the scene jumps to that time in the animation.
The scene updates with your mouse action.
Your scene does not update, but the Current Time Indicator moves to show your new current time. This is useful, for example, if you want to key an object at some frame based on a prior position of other objects. For more information, see Time Slider.
The Range Slider bar lets you control the playback range of your animation up to the limits of the Animation Start/End settings. For more information, see Range Slider.

To move and scale a range of animation with the Time Slider
The selected time range is red, with start and end frames shown in white numbers at the ends of the selection block. See Time Slider.
Turn on
Auto snap keys (Windows > Settings/Preferences > Preferences > Time Slider) to ensure that the keys in the selected range snap to the nearest whole frame. If two keys land on the same frame during scaling, they are merged into one key.
