Once you select a keyframe, it is easy to move and edit it. There are two options for moving keyframes:
- Click and drag with the right mouse button
- Use the G key to move objects around
In the timeline window, and all other parts of Blender, you can use the same shortcut keys to manage selections:
- A key: Select all keyframes
- Alt + A keys: Deselect all keyframes
- B key: Box-select keyframes
- G key: Move keyframes
- S key: Scale keyframe distance
For instance, we can make the entrance of your text a little faster by moving the keyframe from position 24 to 16. Moving two keyframes closer to each other means the animation will be faster.
