A Tactical Wedge

I was examining the keyboard's slope when my boot nudged a stray wooden pencil, sending it rolling straight toward the edge! If it fell, the impact might snap the lead. Thinking quickly, I dashed alongside it and wedged a triangular plastic eraser right into its trajectory. The pencil hit the firm rubber stop with a soft thud and bounced into a resting position against the spacebar. Whew! My reflexes held up, and I managed to secure the area without causing any clutter to tumble to the floor.
