Slipped

He slipped the key into the lock and turned it quietly.

The bag slipped off her shoulder and spilled its contents onto the sidewalk.

He slipped into his pajamas and crawled into bed.

He slipped on the soap in the shower and grabbed onto the curtain to prevent falling.

He slipped a piece of paper into the envelope and sealed it shut.

He slipped on the wet tiles and almost crashed into the wall.
