# Inserting Keyframes

Use the Insert Key button and Duration field to insert keyframes with ripple. Ripple occurs when frames are added or removed, thereby increasing or decreasing the length of the animation curve. You can also insert keyframes at the end of an animation curve.

(a) Keyframe tab(b) Insert Key button(c) Duration field

To set keyframes using the Insert Key button and Duration field:

1. Select the animation curve that you want to affect.
2. Move to the frame where you want to insert a keyframe.
3. Select the Keyframe tab.
4. Click Insert Key. The Insert Key button behaves differently depending on the current frame:
   - If the current frame is the last keyframe, a new keyframe is created <duration> number of frames after the last keyframe (duration is the value in the Duration field). The current frame advances to the new keyframe.
   - If the current frame is a keyframe other than the last keyframe, a new keyframe is created <duration> number of frames after the present keyframe (duration is the value in the Duration field). Other keyframes are moved by the same duration causing a ripple effect.
   - If the current frame is between keyframes, Insert acts the same as the Set button: a new keyframe is created and the duration is unchanged.
