Which key do you press to enable or disable snapping in the timeline?

The key used to enable or disable snapping in the timeline is the 'S' key. Snapping is a crucial feature in video editing software, allowing clips to easily align with one another or snap to markers and other timeline elements. When snapping is enabled, moving a clip near the edge of another will cause it to 'snap' into place, making it easier to align without leaving gaps.

Disabling snapping can be helpful when you need to make precise adjustments that do not align with other clips or markers. The 'S' key allows for a quick toggle of this feature, enabling editors to switch on or off the assistant functionality of snapping based on their needs without having to navigate away from their editing tasks.

Other keys listed do not serve the same function in relation to snapping, and thus are not useful for this specific action within the timeline.
