About
摁 is a phono-semantic compound, combining the semantic hand radical 扌 with the phonetic component 恩. The hand radical indicates that the character denotes a physical action performed with the hand or fingers, specifically, the act of pressing, pushing, or firmly holding something down, as when pressing a button. While 恩 means "grace" on its own, here it serves only to provide the pronunciation and contributes no meaning to the action. The character thus describes a precise, localized movement, emphasizing the use of the fingertips to apply pressure.
