What is the keyboard shortcut for moving one frame at a time in After Effects?

The keyboard shortcut for moving one frame at a time in Adobe After Effects is the Page Up and Page Down keys. This shortcut allows users to navigate through their timeline frame by frame, which is particularly helpful for precise adjustments and editing work. By using these keys, users can quickly and effectively preview their animation or footage in small increments, which enhances their control over timing and placement within the composition.

The other options involve different functions: while the arrow keys can indeed be used for various purposes, they typically move the playhead one pixel at a time rather than one frame. Modifier keys like Alt and Ctrl in combination with the arrow keys do not provide the frame-by-frame navigation that Page Up and Page Down offer, making those options less suitable for this specific task.
