About
The character "键", whose traditional form is "鍵", structurally combines the metal radical with the component "建", originally referring to metal bolts or latches that secured doors or crossbars. Its meaning gradually expanded from these specific hardware objects to encompass anything serving as a crucial fastening or pivotal mechanism, which then allowed it to analogically represent essential components in various contexts. This semantic broadening eventually led to its application for denoting the keys of musical instruments and, subsequently, the buttons on mechanical and electronic input devices, reflecting an adaptation from tangible locking elements to abstract functional interfaces while maintaining its metallic connotations through its radical.
