While you usually need to set one keyframe at a time at the current time, the Key at Time dialog box lets you set one or more keyframes for the selected properties at any point in time, regardless of the current time. Setting more than one keyframe at once removes the need to copy and paste keyframes to create loops, for example.

Besides letting you set multiple keyframes at once, Key at Time is especially useful when you have changed the values of selected properties without first changing the current time. Instead of changing the current time and starting over, you can use Key at Time to set a keyframe at a time other than the current one.

To set a keyframe using Key at Time:

1. Change the values of selected properties, then open the Key at Time dialog box.
2. Enter the frame number at which you want to set a keyframe.
3. Click the Key button or press Enter.

To set multiple keyframes using Key at Time:

1. Change the values of selected properties, then open the Key at Time dialog box.
2. Enter the frame numbers, separating each with a comma () or a slash (/). For example, to set three keyframes at frames 0, 10, and 20, you would type the value “0,10,20” or “0/10/20”.
3. Click the Key button or press Enter.
