What keyboard shortcut adds media to a composition and centers it?

The keyboard shortcut that adds media to a composition and centers it is indeed the combination of Ctrl + /. This shortcut streamlines the process of importing media, allowing users to quickly bring assets into their project without navigating through menus. Once the media is imported, it typically centers itself in the composition, thus saving time and effort that would otherwise be spent on manually adjusting the position.

While other options may relate to different functions within After Effects, none provide the specific capability of centering media upon import. For instance, other keyboard shortcuts like Ctrl + M focus on exporting compositions, while others may pertain to different tools or features that do not involve adding or centering media directly. The efficiency of using Ctrl + / makes it an essential shortcut for users looking to enhance their workflow in After Effects.
