The viewports display
white brackets around objects that have transform keys at the current
time. These key brackets only appear in viewports using the wireframe
Use the Track View to
view all key types. You can also see all keys for the current selection
For example, suppose
you animate a sphere by moving it at frame 20, and scale and rotate
it at frame 50. When you drag the time slider, white brackets appear
around the sphere at frames 50, 20, and 0, and keys appear at the
same frames in the track bar.
If you then apply a modifier
such as Bend, and animate its Angle setting at frame 40, you won't
see a white bracket around the sphere at frame 40, but track bar
displays a key for the Bend animation.

Creating Transform Keys
with the Time Slider
You can use the
time slider to
create transform keys by copying transform values from one time
to another. To specify the type of key to create and the source
and destination time for the key values, right-click the time slider
to display the Create Key dialog.
You set parameters in
the Create Key dialog:
- Source Time
Specifies the time from which
transform values will be copied.
- Destination Time
Specifies the time where the
key will be created.
- Position, Rotation, Scale
Determine which transform
key values will be copied to the destination time.
When you click OK, new
keys for the specified transforms are created at the destination
time, using values from the source time. Keys do not have to exist
at the source frame, because the interpolated values at the frame
You might find it easier
to create and manipulate keys with the
When Auto Key mode is
on, you can right-click and drag the time slider at the same time.
When you do this, the Source time uses the frame number that you
were on when you pressed the mouse button, and the Destination time
accepts the frame number that you move the time slider to.
When Set Key mode is
on, you can right-click and drag the time slider to move to another
frame in time, without losing your character pose. If you find you
have posed your character on the wrong frame, simply right-click and
drag the time slider, and the pose will be copied to the new frame.
Click Set keys to set keys for the pose on the new frame.
Creating Position Lock
Keys and Rotation Lock Keys
Creating a lock key creates
a key with Linear interpolation. If you create the lock key while
an existing key is selected, it changes that key's interpolation
from Smooth to Linear. (Different types of interpolation are described
You can create a lock
key for position or for rotation.
Lock keys are useful
when you want an object to be stationary, but smooth interpolation
is causing it to "wobble" on its stationary spot.
To create a lock key:
- From the Customize menu, choose Customize
- On the Customize User Interface dialog,
click the Quads tab, and then, from the drop-down list at the upper
right of the dialog, choose Animation.
- Click the top-left quadrant of the four
gray squares that comprise the quad menus.
The quad turns yellow.
- In the Action list to the left, find

the object you're animating.
NoteThe Auto Key button need not be on.
- From the quad menu that appears, choose

You can also create keyboard
shortcuts for these two commands. Create Position Lock Key and Create
Rotation Lock Key are main user interface shortcuts. See
