For example, if you're at frame 10 and there are position keys at frame 0, 20,
30, and 50, then editing either a key at frame 0 or 20 with Interactive Update
on potentially lets you see the changes in the viewport as you drag the key.
However, editing a key at frame 50 is unlikely to cause a position change at
the current frame, so you won't see any difference with Interactive Update on
or off.
To view the results of editing keys anywhere in Track View in real time, use
Sync Cursor Time on page 3557 instead. Turning on Sync Cursor Time
automatically turns on Interactive Update as well, so you can see all changes
interactively.
Keep this turned off when you are working in big files and moving large
numbers of keys. Default=Off.
In some circumstances, simply playing back an animation or dragging the
time slider with Track View open, without editing keys, can cause performance
issues. If you experience this, and Interactive Update is on, turn it off to
improve playback performance.
Sync Cursor Time
Track View > Options menu > Sync Cursor Time
Sync Cursor Time Snaps the time slider to the cursor position. When on,
clicking the cursor in the Track View window moves the time slider to that
spot in time. When you release the mouse button, the time slider jumps back
to its previous position.
When off, the time slider does not jump to the cursor position; you need to
click the time slider and move it by hand. Default=Off.
Turning on Sync Cursor Time also turns on
Interactive Update on page 3556 so
you can edit keys anywhere in Track View by dragging them and see your
results right away. The time slider jumps to the frame at which the key resides
and the viewport displays your changes in real time.
Auto Expand
Track View > Options menu > Auto Expand submenu
Auto Expand determines the behavior of the controller window display based
on choices made from a submenu. To turn Auto Expand off with a single click,
choose Manual Navigation from the Options menu: The Auto Expand settings
are then disregarded.
