Tecla Control
Una tecla Control és una tecla d'ordinador modificadora que, quan es prem en conjunció amb una altre tecla, realitza una operació especial (per exemple, Ctrl+Alt+Supr); com la tecla Shift, la tecla Control rarament té alguna funció quan es fa servir sola. La tecla control es troba en el cantó inferior esquerra de la majoria dels teclats. Sol representar-se amb les sigles 'Ctrl' en els teclats, però de vegades s'utilitzen en el seu lloc 'Control' o 'Ctl'.
