This became more acceptable, however, for use in computer terminals at the time, which began to see increasingly shorter model lifespans as they advanced. Multimedia buttons on some keyboards give quick access to the Internet or control the volume of the speakers. On machines running Microsoft Windows, prior to the implementation of the Windows key on keyboards, the typical practice for invoking the “start” button was to hold down the control key and press escape. This process still works in Windows 95, 98, Me, NT 4, 2000, XP, Vista, 7, 8, and 10.
