Tapping the Keys

I heard your loud calls. You shouted my name, then sent a long string of wild letters. I inspected the keyboard to see how that happened. Each square plastic block sank slightly under my foot. I carefully shifted my balance, stepping from 'F' to 'J' to feel the mechanical rebound. The surface tilted, then sprang back. It takes firm pressure to leave a mark here. I am leaving this response before climbing down.
